Yes, something has changes ... still trying to figure out what that something is.
Went to another installation with the same programs running but had no issue.
Only difference was that the system with the problem is running W8.1 and the other W7PRO.
There had been a windows update on the W8.1, but we did a rollback, but this did not help.

Any suggestions on something else to try will be much appreciated!

Thanks, Bill
