I'm trying to get a copy of Acrobat Pro (CS3 version--I think it's 8) to stop crashing on an Intel iMac and I cannot for the life of me figure out where the corrupt pref is. The crashes started after upgrading to 10.5, and happen about 20 seconds after opening it, regardless of what you're doing; the report appears to point to the update checker causing the crash, which would make sense based on the timing. Now, if I create a clean account on the same machine, Acrobat runs fine, so it's got to be a pref issue of some sort. The Adobe Updater run manually also works, as do the other CS3 apps installed. I did also try completely reinstalling CS3, which didn't fix it. Thing is, I've searched for every single user pref with "Adobe" or "Acrobat" in the filename, visible or invisible, folders and files both, and deleted ALL of them, regardless of the app they specify. Caches, plists, user Library application support files (not the root /Library ones, of course), and even after a restart it STILL crashes in exactly the same way. There's GOT to be some oddly named or hidden pref or cache file I'm missing here. Any suggestions?
