... the file that is downloaded is NOT version 3.3. Check the version number. It's 3.2.2. The DMG says it's 3.3 -- but the actual app is 3.2.2. This is where the problems are coming from I think. What people think what they are downloading is not accurate. Now, I don't know if there is in fact an actual 3.3 floating around somewhere that works. But the 3.2.2 version that comes with the 3.3 download (and I've tried many of the mirrors) CRASHES in Panther. The solution for those having this problem is to download the 3.2.2a version as suggested by another poster below. It works pretty good. No crashes. Just a few hangs and hiccups. It doesn't work as good as 3.2.2 (again, the version that comes with the 3.3 download) does in Jaguar, but works well enough until a real 3.3 version, or the next update comes out. Hope this clears things up for people. Not sure why or where the actual 3.3 version can be found. Anyways, great app if you've got a working version!
