I find sometimes viewing flash video with firefox causes the machine to 
appear to hang. In fact killing all instances of npviewer.bin frees 
everything up again. I usually have an xterm open just in case.

Don't have a problem with other apps so this might not be the solution 
for you.

My firefox is 3.6.10, flashplayer is linux-f10-flashplugin-10.1r85 and 
I'm on 8.1R x86
