Status: RESOLVED INCOMPLETE

(Core :: DOM: Editor, defect)

Description

[Nick Cohen]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.8.1.15) Gecko/20080623 Firefox/2.0.0.15
Build Identifier: 5.00.2195 SP4

Using Thunderbird, in the Compose, window, the mouse stops responding after a few lines are written, and when the mouse is not used.  It is necessary to reboot the computer to restore operation of the mouse.  Restarting T-bird alone will not do the job.I usually have to compose for a minute, or more for the effect to manifest itself.  If I don't type, it doesn't happen.  If I frequently use the mouse, it doesn't happen.  Can't associate the effect with the use of any particular character.  The cursor remains visible.  It is possible to complete the message, send it, and restart the computer using the keyboard alone.
  The mouse has failed during the composition of this message, on this form  I should be able to restart in Hibernate mode in order to complete this message.
   Did so, successfully.

Reproducible: Always

Steps to Reproduce:
1.  Enter Compose window
2.  Type a few (4, or more)  lines
3.  Do not use the mouse
Actual Results:  
See above.

Expected Results:  
See above.  Mouse should continue to operate normally.

Computer is a year 2000 vintage IBM 300 PL, w. 500 MHz, Intel Pentium III processor.

Thunderbird shouldn't be doing anything special with the mouse, so I have a hard time seeing how this could be a bug in Thunderbird (nor do I have any idea how to narrow it down if it is).

Does your mouse ever lock up otherwise?  Does unplugging the mouse and plugging it back in fix the problem?  Does the mouse need to be in the compose window somewhere in order to exhibit the problem?

Steve,
     The mouse locks up only when composing in a Mozilla window, including this one in Bugzilla.  The pointer can be anywhere, and not necessarily on the "Compose" window.  The cursor, of course, is always in the "Compose" window.  I will do an experiment to see if it happens in Explorer/Outlook.  Unplugging the mouse, and re-plugging it has no effect.
     This message was not long enough to make it happen, but that is not necessarily the case.  Oops, now it is!  Be back shortly.
     Does not seem to be a problem in Outlook.  Maybe some Microsoft jamming?

Ok, so you get the same problem in Firefox text boxes?

Comment 4

[Nick Cohen]

Yes.

In that case, I'm going to move it from Thunderbird to Core, since it's not specific to TB.

Nick does this still reproduce for you?
