Microsoft mouse wheel scrolling does not begin working until cursor is located over right hand scroll bar, and the mouse wheel itself is clicked. One IE 5.0, mouse scrolling is always activated on all pages.

Reassigning to bryner@uiuc.edu who is the mouse wheel scrolling guru. robertgee@worldnet.att.net, can you give more information about your system? Please read the Bug writing guidelines at <http://www.mozilla.org/quality/bug-writing-guidelines.html>

Just to note that I am looking at this, but I can't do anything until you give some more information, including: Mozilla build version Mouse driver version Also, are you referring to regular wheel scrolling or to the "wheel-pressed" mode where you hold down the wheel button and move the mouse?

Hi, I am using a Micron Millennia PC and Windows NT4 SP4 with a Micron branded Microsoft scroll wheel mouse using "Pointer device using msi8042". Mozilla is M14 build 2000022820. Just bring up www.news.com, and the scroll wheel will not work. Pressing the scroll wheel itself will allow the page to scroll by physically moving the mouse which is not what I wanted. I really want to scroll the HTML page with the scroll wheel only. If you need more information, please feel free to send me an e-mail. Thanks.

Can you take a look on a current nightly build (i.e. 03-16-2000-M15 or later) and let me know if this is still happening? The problems you're describing sound similar to bugs 22794, 25708, and 20618. You might also want to see the comments I added to those bugs about the logging option I just added to the nightly builds.

robertgee@worldnet.att.net: Can you please update the status on this bug, when you have a chance? Thanks.
In case robertgee@worldnet.att.net doesnt respond... with build 2000033116 the problem is still evident. Scrolling the mouswheel does not scroll the page. If you click on the main scroll bar with the mousewheel then the page does scroll as you move the mouse up and down. It continues to move with the mouse movement until you left (or right) click in the document. Kinda weird. Also you can scroll selection boxes like the ones in http://bugzilla.mozilla.org/query.cgi normally. Heres my pertinent hardware/software: Win95b, Microsoft PS2 IntelliMouse with Intellieye, Microsoft IntelliPoint 3.0 (I might have upgraded to 3.1a, can't remeber) driver which runs a deamon called Point32. I'll check out the logging thing in the nightly builds next :-)
I take back what I said. I don't understand the logging stuff in the other bugs. Do you have to build Moz to do that or can you enable it in a binary? To be honest I don't even have a compiler installed in windows.

No, you don't have to build Mozilla to use the logging. Just go to an MS-DOS prompt, type: set NSPR_LOG_MODULES=MOUSEWHEEL:5 then cd to the mozilla directory and run: mozilla > mozilla.log The mozilla.log file will contain the logging information, if anything got logged. From your description, I'm wondering if this is really the same as all of the other "scrolling doesn't work" bugs, and the scrollbar thing is simply a workaround. See bugs 32226, 20618, 22794, and 25708. If one of those other bugs describes this bug I would rather not keep this one open.
Wow! this is cool stuff. I got your copy of gkwidget.dll working! I renamed the original gkwidget.dll to something else and put yours in it's place. I then loaded mozilla with the "> mozilla.log" option. Then I let mozilla come up and I moved the Mousewheel down once. I then closed Mozilla with alt-F4. An examination of the .log file produced this line early on: "Registered MSH_MOUSEWHEEL = 52347" and then the fifth to last line:"nsWindow received MSH_MOUSEWHEEL, HWND=608" Pretty cool. OK, I just tried the same experiment except I scrolled the mouswheel up once. It was identical except the fifth to last line was now:"nsWindow received MSH_MOUSEWHEEL, HWND=2376" Playing around some more... it seems the HWND number is arbitrary. Each time I bring up mozilla, move the mouse wheel and then look at the log file, it seems to be a differant number regardless of wether I moved the wheel up or down. For example, moving it up once then down once made these to lines in the .log file: nsWindow received MSH_MOUSEWHEEL, HWND=3592 nsWindow received MSH_MOUSEWHEEL, HWND=3592 if I do the same thing again... nsWindow received MSH_MOUSEWHEEL, HWND=3248 nsWindow received MSH_MOUSEWHEEL, HWND=3248 I don't get it, what is the significance of the numbers? I took a look at the four bugs you mentioned. I don't think this bug is a dup of 32226 (both Microsoft mice yes, but that bug is intermittent for some reason, while this bug is constant). I've looked at the other three briefly but I'll have to look in them more deeply later.

Ok, so.... you are seeing the MSH_MOUSEWHEEL messages, but the content area is not scrolling? This could be important, as it means I know where to look now for the bug. Were there any additional lines printed after you moved the mousewheel?
Comment 11•24 years ago

No, no lines are printed after moving the scroll wheel aside from the usual nsWindow received MSH_MOUSEWHEEL, HWND=XXXX Interestingly, clicking the mouswheel causes "OH MY GOD!" to be printed out?! By the way, everything works fine when gfx scrollbars are turned off.

As of the nightly build of April 4, 2000, this bug appears to have been fixed.

fisher7@thegrid.net: I've updated the version of gkwidget.dll at http://www.productivity.org/~bryner/mozilla/gkwidget.dll to include different debugging information. I'm especially interested to see what it prints for you, since it looks like we get really close to handling the scroll correctly but then it somehow does not. So please give it a try when you have a chance. Thanks.

Updated gkwidget.dll again, only change is to remove some extraneous debugging output that was printing out even when there was no mousewheel movement.

I'll download the April 4, 2000 build to see if it works as per robertgee@worldnet.att.net 's comment. Also, I took a look at the three other bugs. I suggest we move over to bug 20618 (not a perfect match but close enough) since this bug is closed.

I compiled that against the current source... are you running the 04-05 nightly?
Comment 17•24 years ago

Oh, no wonder :-) OK, running with build 2000040415 with new gkwidget.dll, scrolled mousewheel down once, up once, and down once. Then closed program. The log file: Document: Done (4.62 secs) Processing mousewheel message Getting scroll lines Got iDeltaPerLine=0 Processing mousewheel message Got iDeltaPerLine=0 Processing mousewheel message Got iDeltaPerLine=0 WEBSHELL- = 2 WEBSHELL- = 1 ~nsProfile WEBSHELL- = 0

Ah, that would do it! Looks like we're failing to read the system setting for number of lines to scroll, and therefore bailing. I think I need to make separate cases for WM_MOUSEWHEEL and MSH_MOUSEWHEEL to read the number of lines. Will try to get that done in the next couple of days. (I'll put up a new gkwidget.dll and update this bug so you can check it out before I check it into the tree).

Awesome! Awaiting your word...
Comment 20•24 years ago

Ok, no guarantees, but I just uploaded a new gkwidget.dll that attempts to properly detect the system setting for the number of lines to scroll on Win95. Give it a shot.

Congratulations! It works beautifully! Thank you! Here's the log from one mouse scroll: Document http://www.mozilla.org/ loaded successfully Document: Done (4.56 secs) Processing mousewheel message Getting scroll lines Using Win95 mousewheel handling Got mswheel hwnd Registered MSH_SCROLL_LINES Got ulScrollLines = 3 Got iDeltaPerLine=40 Dispatching message to another window Giving message to window with hWnd=744 Processing mousewheel message Got iDeltaPerLine=40 Setting scrollEvent.deltaLines=-3 Calling DispatchWindowEvent for mousewheel message WEBSHELL- = 2 WEBSHELL- = 1 ~nsProfile WEBSHELL- = 0 The "click the mousewheel scrolling" doesn't work, but I bet you knew that already. Thanks again...

Congratulations to bryner and fisher7 for their great work! I can't wait to download Netscape 6 Preview 1. Maybe in the future, I can contribute my C++ development skills instead of just testing.
Comment 23•24 years ago

Thanks. You should note, though, that Netscape 6.0 PR1 was branched off several weeks ago and so won't contain any of the recent fixes.
