I recently noticed that Mozilla seomtimes refuses scrolling a page by mouse
wheel and keyboard, the scroll bars, however, work. But - in rare cases - not
even these work. I may click-and_drag the bars, but clicking the area with nor
bar actually in results in ... guess ... nothing. The same applies to
<textarea>/<select> scroll bars. <select> list may, however, by crawled by using
the keyboard's UP/DOWN/PGUP/PGDOWN keys. I cannot exactly tell what
circumstances are affecting the browser to do so, but I'll try to figure out.

I've the Tabbrowser Extensions installed. The behavior seems to only come up
when multiple tabs are opened at the same time (I guess around 8+) and the
system has undergone some heavy load. After the first tab is 'visibly locked' it
sometime seems the effect spreads over to other tabs as well.

The effect is not aware of the pages which are 'locked' having frames, DHTML or
whatever. It may happen anytime anywhere. But: ofter there are forms on the
pages that get 'locked'.

Reproducible: Didn't try
Steps to Reproduce:
1. Use Mozilla as usual
2. Open some tabs (6,7,8 ...)
3. Make your box have load (???)
4. Be unable to scroll some pages...

Actual Results:  
Simetimes 'visual locked' pages

Expected Results:  
Scroll ;)

I'll update to the current CVS later today to see if the problem persists. As
the recent checkins do not promise any change to the behavior. But, hey ... the
change went in with no 'hint' as well...

Happy hacking, folks. I would if I just could. ;)

I don't think so. I does not only affect any <DIV> or whatever. It affects the
whole visible area as well as <TEXTAREA> (!) / <SELECT> (!) elements.
