It's locked up on me about a half dozen or so times in the past week. 
Additionally, the box suspends at random times[1] (it's not a laptop) 
and cannot be brought back out of it.

Also, Thunderbird and Firefox occasionally cannot display certain images 
properly[2] and Thunderbird crashes if I try to paste text that's been 
copied from either the terminal or jEdit. Yup, lots of nasty bugginess. 
I don't know what else to check and don't think I can deal with this 
much longer.
