The quickest way is to restore half of your apps. If it works well then restore half of the remaining apps and so on. This technic is the quickest logical elimination process for finding the bad app or file etc. whenever trouble shooting computers.
I really think I found the culprit this time. I have Quicken and I bought PocketQuicken 2.5. My Quicken got corrupted some way, and apparently corrupted PQ also. I uninstalled and reinstalled both and have had no problems since
