Thanks for the reply.   When I choose "switch to or retry" it just keeps on spinning. They only way I get into the program is to do a total shutdown.  Yes, I am running a few programs but so aren't the other people in my firm with no issue.  We have same computers, programs etc.  Its very strange how it only effects a few computers and not all.  Not sure about the auto-backup program but will mention it to our IT specialist.  Thanks for the help.
