Jim, Have you verified that the version bundled should work on your mac? See if it opens if the computer is in safe boot. If it does, there is an extension conflict.. Might it open if you create a brand new account? Lee On Jan 5, 2009, at 1423, James Hurley wrote: I just got a copy of acrobat professional with a SnapScan scanner.

Any thoughts on this opening and quickly closing problem? Jim -------------- next part -------------- A non-text attachment was scrubbed...
