72606 - Dragging link to other window breaks mouseover detection

Status: RESOLVED WORKSFORME

(Core :: DOM: UI Events & Focus Handling, defect)

Description

[Andreas Premstaller]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; 0.8.1) Gecko/20010316
BuildID:    2001031604

After dragging a link from one browser window to another browser window, a right
mouse click in the original window does not work anymore and link titles are not
displayed anymore.

Reproducible: Always
Steps to Reproduce:
1. goto above url, the bug numbers usually have a link title popping up when
mouseovering (thank you, asa!)
2. open a second browser window
3. drag any link from the first browser window to the second one

Actual Results:  When you now hover over the links in the first window, the link
title is not shown anymore. Moreover, if you try to right click on any of the
links, the context menu is not shown.

Expected Results:  Link titles should still be shown, right click should work
correctly.

1. Functionality is restored after you reload the page.
2. If you minimize the second window, link titles and right mouse work correctly
again in the original window.
3. Clicking around the window wildly (left and right) sometimes helps to restore
right mouse button operation, afterwards link title works too.
4. No problem occurs if you use "open link in new window"

No problem on LINUX. Everything works fine.

Thanks for checking.

I still see this using Build 2001040304 with Win2000 (well, today no tooltips
are shown at all, but the right mouse buttom behaviour is the same).

In the meantime I did a completely new install of Mozilla (delete mozreg.dat,
all program and personal folders), it did not change the situation.
Maybe it is Windows-specific?

Have you tried completely removing and reinstalling Mozilla does that fix the
problem?

I still see this with 2001040904 on W2K. Yes, clean install with new profile
(see 04/03). I also do not see link titles any more now (at least since 04/03).

I investigated this a little further.

I see this behaviour everytime that I drag a link to an open browser window.
Afterwards, it seems that mouseover in the original window is not detected (or
notified) any more. No context menues with the right mouse buttom anywhere on
the site (links, images, text), no link titles, and no update of the url in
status line if hovering over a link.

However, full functionality is recovered if you move the mouse over the
navigation or personal toolbar.

Interestingly, only the original window is affected. The window where I dragged
the link to and all the others are functioning normally all the time.

Is event handling the right component for this?

Ok, I'll continue my monolog here.

Using Build 2001041704 on W2K, I only lose the first mouseover-event in the
content area of the original window any more. That is, the second right
mouse-click now works, and the second link you mouseover to display the link
title works too. 

Who knows, maybe that will go away soon, too (hopefully).

This bug has been marked "future" because the original netscape engineer
working on this is over-burdened. If you feel this is an error, that you or
another known resource will be working on this bug,or if it blocks your work
in some way -- please attach your concern to the bug for reconsideration.
