DOS Application under Win XP Pro

DOS/FoxPRO application is using all the CPU utilization and all the available memory under Win XP Pro.

The application was tested on Netware 3.12 and also copying the application on a local HD under Win XP. The application runs fine under Win 98SE.

Also tried different options of Win XP compatibility mode for Win 95 but none seems to be reducing the CPU utilization and memory usage.

Can any one help how to run DOS application under XP without allocating entire memory and CPU cycles.
