79968 - Inactive window closes other windows when dragged over close button

Status: RESOLVED DUPLICATE of bug 103031

(Core :: XUL, defect)

Description

[Adam]

(2001-05-09, Mac OS X, v10.0.3)

The hidden window seems to destroy other windows if they are dragged 
into the area it occupies. If you drag the top-left edge of a window over the 
hidden window (the top-left of the screen), the window disappears.


1) Open a window (Manage Bookmarks window is a good one to use)
2) Drag it to the top-left of the screen
3) Poof!

You might have to be a little precise with the location - I have my main 
browser window set almost flush with the top-left of the screen, and I have 
to drag a window so that its top-left edge is in the middle of the red 
"Close" button for this to work. The only thing I can attribute this to is the 
stupid hidden window that's in that corner (and usually quite visible).

Actually, it appears to be the inactive window that's causing problems. 
With a browser window already open, try dragging a different window so 
that the top-left corner of the window is directly over the browser window's 
close button. As soon as you let go of the mouse button, the window is 
closed. Updating summary.

1) Begin a file download
2) Drag the download window's upper-left corner over a browser window's close button

The download progress window closes, but the download continues. Without a UI
for the progress, a user won't know when a download is really finished. Also,
since most users will think the download aborted, they'll just ignore it and try
to download the file again or do some browsing - a problem on slow connections
since the download is still going and sucking up most of the bandwidth. So you
either have to wait until the download is finished (whenever that might be) or
you have to quit and relaunch the browser just to abort the download (like I
have to do right after I submit this comment).

Is that (and the fact that those of us who like to stay organized can't tile our
windows) enough of a problem to raise the priority to 0.9.3?

I can't repro this in the N6.1 for OS X Preview.  Is it still valid?

Comment 5

[Adam]

I'm still seeing this problem in the 8/27 nightly.

Strange things also happen if you drag the top left corner of the active window
over an inactive window's maximize button (green plus-sign button). One or both
of the windows changes position.

danm doesn't have an osx box. dagley? care to take a look. i can duplicate this 
now, and yeah, i can see how it could be annoying. the finder doesn't do this. i 
wonder why we do.

Also, under some circumstances (I haven't pinned down the conditions exactly)
after dragging the active window, it will jump upward, leaving the title bar
outside the screen area (and making it impossible to move the window).

THis may be a separate bug.

Comment 10

[J Luh]

The description of this bug is a little confusing, which makes it hard to find.
How about:

"Active browser window jumps or disappears when dragged over inactive browser
window"

Comment 11

[Steve Dagley]

I have never been able to repro this.  Can anyone that _has_ seen it try again
now that 10.1 is out and see if it cures the problem?

Comment 12

[J Luh]

I have a fresh install of Mac OS X 10.1 and I still run into this problem with
0.9.4 build 2001100205, as described in my earlier comments. I am still
experiencing all three problems (windows unexpectedly closing, maximizing, or
changing position so that their title bars are offscreen)

Comment 13

[Mike Pinkerton (not reading bugmail)]

yes, it still happens with 10.1, branch bits from 10/2

"Also, under some circumstances (I haven't pinned down the conditions exactly)

outside the screen area (and making it impossible to move the window)."

I have seen this also.   To fix this, I have to change the display settings to
cause the title bar to be visible on screen again.

On 10.1, 2001091313 I reproduced the close problem the first time I tried it and
now it doesn't occur again.  Can't reproduce minimize or maximize.  FWIW.

Here are steps that will reproduce the window jumping problem:

(Using Mozilla 0.9.4 build 2001100605 on Mac OS X 10.1 on a Powerbook G4)
1. Create a new profile.2. Close the Navigator window.
3. Open an Editor window.
4. Open an Address Book; dismiss dialogs by clicking Cancel and Exit.
5. Move the Address Book window to about the position shown in the attached
screen shot.
6. Click on the title bar of the Editor window.7. Click on the title bar of the
Address Book Window.

The Address Book window jumps upward.

Also, if you repeat the steps above but skip step 2 (leaving the navigator
window open), the editor window will close by itself on step 6.

Any chance this can be fixed by Mozilla 0.9.6? It's very annoying.

Comment 18

Here is a third variation on the steps from my earlier comment. These steps will
reproduce the window-jumping problem while dragging:

1. Create a new profile.
2. File->New->Blank Page to Edit.
3. Open Address Book. Click Cancel and Exit to dismiss dialogs.
4. Click in the content area of the Editor window (not on the title bar) to
bring it to the front.
5. Click in the content area of the Address Book window.
6. Drag the Address Book window to the position shown in the screen shot and
release the mouse button.

The window jumps upward; the title bar is off the screen.

Comment 19

[J Luh]

Simpler steps to reproduce:

1. Create a new profile; launch Mozilla.
2. File->New Blank Page to Edit.
3. Click on title bar of Navigator window to bring it to the front.
4. Drag Navigator window to magic spot shown in screen shot.

Navigator window jumps.

Comment 20

[Steve Dagley]

This bug is for Inactive windows closing other windows, not windows jumping 
around.  Please file another bug for that as all those repro cases do NOT result 
in the inactive window closing (or at least not fo me - I do get a window that 
ends up partly offscreen)

Comment 21

[J Luh]

I have filed two additional bug reports, bug 103770 and bug 103771, to cover the
cases where windows maximize or jump unexpectedly.

Comment 22

[Steve Dagley]

Now that the jumping window bug has been broken out I'm going to close this one 
as a dupe of 103031 as that bug is a little more specific to disappearing windows
