248283 - Firefox hangs when a dialog pops up while dragging text

Status: VERIFIED DUPLICATE of bug 246801

(Firefox :: General, defect)

Description

[Richard Harris]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040614 Firefox/0.8
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040614 Firefox/0.8

If a standard MsgBox-esque dialog appears whilst you are dragging text with the
mouse, you will be unable to dismiss the dialog (OK button is non-responsive)
and the whole browser hangs.

Reproducible: Always
Steps to Reproduce:
1. Visit a normal site such as http://www.yahoo.com/ .
2. Find a site that is non-responsive and will timeout, and access it. E.g.
enter http://www.dgewreqtqwr.com/ or some equally ridiculous domain in.
2. While this is loading select some text and drag it away.
3. The 'site.com could not be found' dialog will pop-up, browser crashes.

Actual Results:  
Hung and can only be closed via Task Manager. However, the tab loading the
non-existent site has an animated icon (the swirling arrows).

Expected Results:  
Allowed me to dismiss the dialog, losing the selected text.

Using Charamel theme, WinXP 1.8 AthlonXP w/ 512mb RAM. Will confirm if it occurs
with standard theme shortly.

Same thing like in bugs Bug 246801 and Bug 244702. Duping? Looks similiar to Bug
210819 too.
