heyas; didja see my reply on your other post? it seemed to happen to me when i had the joint editor window open. also, i know you re-installed, but did you put the patch on? mine went way after a while (either i quit using the jp window, or i put the patch on ;) ) also, the messed up thumbnail doesn't seem to affect the character, so as long as you read the name and know who it is, you're okay.
