Just thought I'd upload a universal version of Xee 1.2.1. I couldn't find one and I can't stand the Rosetta load time. YUV decoding doesn't seem to work so go into prefs > advanced and set it to use RGB.
Here's a link:

Can't wait for the anti-aliasing build, though I checked out preview and it doesn't seem to anti-alias either. It only seems to do that for PDF documents. Xee alpha 2 crashed my Intel Mac too as soon as it launched. You'd have thought there would be some way that the system would auto-recover from a graphics driver crash.
