>Update on the problem. We rebooted the machine in safe mode and ran the program and there were no errors. Rebooted back into normal mode and ran the program successfully. It appears to be working now but I have no idea why which bothers me greatly since many of our customers will have similiar machines. Any ideas??

I have seen bizarre problem related to video drivers. Knocking the driver back to a plain vga/svga can help. Updated drivers from manufactorers can help.
