Well, I have spent a good portion of this morning trying to troubleshoot the damn freezing problems I've been having with my new video card. I'm now convinced it's a driver problem...either with the ATI driver or the damn Ali Magik chipset AGP driver, or a conflict between the two.
I can enable transparency in Trillian now without it crashing, but only in certain video modes. Anything less than 1024x768 16-bit color works just fine...anything higher than that crashes. I think it's mainly dependent on color depth, because even 800x600 in 32 bit color will cause the freeze. To o bad for me, though, because I like running in 1152x864 with 32 bit color. Crap.
I guess I just have to wait for the bastards to put out a driver that actually works with my motherboard. I'm really starting to dislike ATI...if these problems don't get fixed soon I may never buy another one of their cards. Maybe I need to make some phone calls. :(
