Yes, but I've done a wholesale redesign of the bitmap handling objects since then, and I don't have the image writing code (to file) implemented yet. When I do get it written, then [GV]FM will be able to store to and from different image formats much much easier than what it would have taken to do this in the older versions.

There are only two things in GVFM that deal with Windows:

(1) The System Information dialog box.

(2) The start-up code that reprograms the Programmable Interrupt Timer (PIT) to run at twice its normal 18.2Hz frequency if Win9x/ME is detected. This has to be done to kick-start Windows9x/ME into allowing GV[FM] hardware access to the timers. I could make GVFM always do this, but there is a very small chance that doing so might be incompatible with a real DOS or a DOS driver.

That's it. Nothing else cares.

Yes I could do that. I might even be able to make it more generic than that, since the Win98 DPMI server doesn't support 31h/0401h - Get DPMI capabilities, and if all the other Windows servers don't either, and all other commonly used servers do...

That would obviously be the best solution.
