We have some legacy DOS applications which we are testing for XP compatibility. The test PC is a Dell workstation, running XP Pro with SP2.
The problem is that the application runs for a while and then goes to a blank screen for (perhaps) 10 seconds before returning to either the XP Desktop or another open application (e.g. a Word document). In either case, the DOS application has a minimised entry on the Task Bar, which when clicked will return to the DOS application.
The minimising can occur during input, but more often after/during the printing of a report. The time before the application minimises in not constant (sometimes 3 hours, other times 10 minutes) and I have turned off the screensaver.
Any suggestions would be welcome!
