DeskCNC will normally not be disrupted, in the worst case, only
delayed. There is a 212 command fifo buffer in the controller
card. The commands are complex positioning commands NOT step and
direction. If the buffer should empty while windows does it's
thing, the machine stops gracefully, and the controller awaits
additional commands, it does not lose it's mind or position.

I have no reports of this happening with DeskCNC running in Windows
XP.

There are still programs around that cause this kind of problem,
usually 16 bit Win applications from the Windows 3.1 and 95 days,
not very many 32 bit applications.
