It is a fault of your windows drivers, mostly likely the graphics ones. Most win95 systems don't have any problem with suspending an SVGA DOS program (it works perfectly on my machine, for instance), but some drivers just don't bother to implement the save and restore state functions. I don't know any way to fix this. Shawn Hargreaves.
