I've never seen this one before, but using FF3 on OpenSuse 11.0 (started with KDE4 and continued with KDE4.1) if I place an "x" or a checkmark on a box, such as in Yahoo Mail to delete a mail, the "x" doesn't display unless I click somewhere outside the box. It also will not complete the action if the checkmark is not shown. Happens in all web mail.

Also, cannot display certain video or play web-based music like in MySpace. Am using Kaffeine, Xine and Mplayer.

Plugins are:

Xine
VLC
Mplayer
Real Audio
Flash
Adobe (acroread)
Quicktime
Windows Multimedia
Google VLC
Helix
Kaffeine

Some videos will play, but frequently embedded videos will not. YouTube works fine.

Thanks in advance for any help.
