The page source attached to this report is for a web-mail 'New Mail' page. Bug
is present in Mozilla RC1/RC2. Theme used is Modern, have not attempted
reproducing bug with other themes.
If you copy the HTML code from the 'Additional Information' into a file and then
open it, the problem will occur after you set the mouse cursor in the main
textarea of the page, right where you'd normally type your message. After the
focus is set, the keyboard response becomes incredibly sluggish (try typing some
text in that textarea), and switching to and from that Mozilla window will be
accompanied by a pause. However, if you type your message elsewhere (i.e.
Notepad) and then paste it into the textarea, the response is acceptable.
Some elements (hidden form fields) containing the username/password details have
been removed from the page source code for obvious reasons, but that should not
affect duplicating the problem.
Reproducible: Always
Steps to Reproduce:
1. Copy and paste the code from 'Additional Information' into a new HTML file.
2. Open the file in Mozilla.
3. Set mouse cursor in the main text area (message body) and try typing a
sentence or two - the keyboard response should be quite bad.
4. Alt-tab to a different Mozilla window and then back to the original one -
there will be a delay.
5. Create some text in Notepad and then paste it into the area where the
keyboard response slows down - this should work OK.
Actual Results: See above.
Expected Results: Normal/usual behaviour (no keyboard delay, no task-switching
delay)
This is the code that accompanies the bug report

could you please add the page as an attachment... It is easier to view then so
we can determine what is going on.
No, it does not seem that Bugzilla will let me add an attachement - it throws an
error saying that I'm not logged on, and then claims there's no file to include.
If someone else could copy the page source and paste it into an attachment, I
would appreciate it.

The error shows up only when the page is fully loaded (ie. all the images etc).
If you attempt using the text area before the images are loaded, it seems to
work OK.
