Nukeboy - I don't have Tweak UI, but I find regedit to be about as helpful in these situations. Although I can't believe it myself, I don't believe Poser creates reg entries, as none of them exist in any program directory, or come up in a search. Thanks, though! Eric - After uninstalling, I deleted the main "Curious Labs" directory entirely. I don't keep my actual poser files in there, so I decided that it just wouldn't be that big of a deal to reinstall everything. I haven't thought of running scandisk or defrag yet - I'll definitely look into that! Pretty much the only other thing I can come up with at this point is that some config or DLL file in the Windows directory itself (or system32, whatever!) has become corrupted, and for some reason (maybe because it is shared (maybe why it became corrupted in the first place?)) isn't getting uninstalled along with the rest of Poser. If that's true, however, I'm screwed. At any rate, thank you so much for your suggestions! Aaron
