Tooltips (created by putting a "title=" field inside a link tag) take something like 3 or 4 seconds to appear. On Internet Explorer, they only take about 1 second. This seems much more reasonable. I'm using Mozilla v1.1b: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.1b) Gecko/20020721 Also, note that I'm using a fast (PIII/576MB) machine, so this isn't a problem with the system's processing power or anything like that.
WORKSFORME. Tooltip from a TITLE attribute only takes about 1 second on my system. Build 2002080918, Win98.
I thought that kTooltipShowTime is defined as 0.5 seconds ? Even with all the different processing that's going on (creating the window, etc ...), it shouldn't take much longer than a second or so. On my 300MHz Mac (Mac OS 9, build 2002080908), it takes less than 1 second to popup a tooltip. I'm using the pages on my website (www.bluesweb.org) as a test. For instance http://www.bluesweb.org/calendar.phtml : evey blue link that you see, has a popup associated with it. I was even looking ofor a way to slow down it somewhat, since it's a bit annoying if you slowly move across the page. Reporter: can you give us a page where it takes so long ? And can you go to http://www.bluesweb.org/calendar.phtml to try it out ?

Hmmm... Jo, even on your page, the tooltips take >3 seconds to pop up. Also on my page at www.NoDivisions.com under the "Last 5 visitors" section... all the links there have tooltip popups. So: It works for Jo (Mac/build 2002080908), and for Warner (Win98/build 2002080918), but not for me (WinXP/build 2002072104). I'll download the latest nightly build and see what I get.
I installed the latest build, and that didn't fix it. So I rebooted my machine (it had been running for ~3 weeks), and that DID fix it. So... is that a Mozilla problem, or a WinXP problem?
As long as Mozilla wasn't running for 3 weeks, it must have been Windows XP (some kind of background cruft that running and stealing cycles).
Reporter: did you check CPU consumption while the problem had been happening? That usually happens when some stray process consumes a sufficient amount of CPU time...
Yes I did -- my CPU wasn't being heavily utilized (~5%, or "normal" at idle). Also... I had previously reported that rebooting fixed the problem. Well, it did, temporarily... but a short while later (less than an hour), the problem was back again.
Anthony, could you check the handle count and GDI object count for the mozilla process and for other processes on the computer... something is wrong if the handle count keeps growing as you use the program. With a browser and mail window open, my handle count is ~220 and GDI objects is ~500. These numbers can be found in the Task Manager (right-click on the taskbar).
OK, I boot and run only Mozilla. Mozilla has 130 handles and 116 GDI objects. Total handles is 4870 (!) and total GDIs is ~600. This is after I've closed everything that's running in the taskbar (AntiVirus stuff, Proxomitron, OpenOffice quickstart, etc.) Here are the worst handle hogs... note that they're all Windows processes, not 3rd party apps: svchost.exe: 1224 explorer.exe: 758 winlogon.exe: 433 csrss.exe: 322 services.exe: 284 System: 266 lsass.exe: 251 svchost.exe 214 (yes there are multiple svchost.exe processes)

Anthony, is this still a problem in recent Mozilla versions?
Yes. I'm using build ID 2003020408 and it's still a problem. It takes 1.5 - 2 seconds for them to appear. And for some additional weirdness, there are times when they pop up with no delay. (That is to say, "normally"... I don't mean "instantly.") This has happened maybe 5 times that I can remember, and there is no pattern that I can see. As soon as it happens, I think "what did I just do? Did I close some certain webpage, exit some other program... WHAT WAS IT??" But I still have no idea.
Are you up to date with Microsoft updates? What video card do you have, and is the driver recent? In the Display Settings, Advanced, under Troubleshooting: how is the driver acceleration set? Try changing this setting and see what happens. Have you tried a new Mozilla profile? Just trying to think of some reasons you'd be having this problem.

Argh... I wish I could say that one of those things worked. All the latest MS updates have been installed. I just uninstalled Mozilla, then deleted the Program Files folder, then deleted my user profile folder (in the "Documents and Settings" folder), then deleted anything Mozilla-related in the registry's hkcu\software and hklm\software keys. Then I re-installed Mozilla build 2003020408. Problem still exists. I just downloaded the latest video driver for my ATi Radeon All-In-Wonder 7500 AGP (which included 3 files: a WDM tv-capture setup, the actual driver setup, and then an ATi control panel setup). Rebooted about nineteen times in the process (I hate Windows). Problem still exists. I adjusted the display driver acceleration, down from "full" to just above halfway. Problem still exists. This is a real bugger of a problem, and as with so many Windows-related bugs, I have a feeling it's going to be a "reinstalling Windows fixed it" bug. Did I mention that I hate Windows?
Another strange timing issue I have is that meta refreshes take too long. For example, if I make a webpage that has this in the head: <meta http-equiv="refresh" content="5"> ...it doesn't refresh in 5 seconds. It always takes 10 or more seconds. Even when I put the URL in the "content=" setting (which IIRC is the to-spec way of doing it). Any thoughts on that, and on whether these two timing issues are related? In both cases, things are taking longer than they're supposed to.
That might be it. Though most people with weird timing problems have Mozilla going way too _fast_. See bug 185741, bug 187512, bug 184263
Sick. Maybe we can get the guys who wrote the "too fast" bug to talk to the guys who wrote the "too slow" bug and they can engineer a "just right" bug for us. In any event, I'm glad I'm not the only one... there are apparently some strange things going on with timing in Mozilla.
Hello everyone, I just re-installed Windows XP on my machine, and the problem is gone. Like so many others, this was one of those bizarre unsolved-mystery Windows bugs. Thanks for all your suggestions. Any further comments before I close this bug?
Closing as WFM per prior comment. If the problem crops up again, please let us know.
