Sorry about Necro Posting.
Here is the issue I am having. Adobe Illustrator CS4 passes all the plugin checks, and loads the frame of the "Welcome Box." After a few seconds, the program closes without any warning messages. If I click the title bar, it displays (Not Responding). If I open any ai file, it displays it, then closes.
I have done everything short of reformatting, and i really don't want to do that again. I checked my event log, it is an app hang, 1000(100).

*EDIT*
Well, I just tried it again, and the problem has finally solved itself. I wish I could be of more help to figure out why it was happening though. I'll keep my eyes peeled and post here if i learn more. I was going to create a dump file, so I had task manager open when I started AI up this time... which means AI wasn't in focus... maybe that has something to do with it?
