See my previous posts on my resolution.....
Check and make sure you do not have orphaned program files, especially from all the Adobe products. This was the culprit in my case. Removing all those files and repairing permissions resolved my start up issue.
During termination of the program, you may encounter a bit of a delay if you have many cached images. I have it set to clear out the cache so it allows the program to quit almost immediately.
Hope this helps
