The current version of the program has been in use for two months, getting run about 400 times a week (3200 runs). The previous version did not use the Oracle server, it read .txt files. Testing of the current version was minimal, as the previous version has been in use for 3 years. I only enabled the "Unattended Server Mode" 2 weeks ago, and I have run into this problem 2 times in the last 800 runs. It is worth noting that we were having Oracle performance problems.

AHA!!!!!! When you run a report form, there *is* UI. The standard VFP printing "Printing..." dialog will be displayed, or in this case, attempted. There is nothing you can do to suppress it.
