"PMVDesk is a Virtual Desktop utility for the OS/2 2.x Workplace Shell. When you start the program you will see a 9 button grid. Each button represents a screen (of your current video adapter resolution). "
The source code is now open source for people to adapt the work or learn from it. There is also PMVDesk Pro which was an unreleased re-implementation of PMVDesk, the source code is also available for the public.
Special thanks to Carrick von Schoultz for making his software open source.
