Interesting...  I haven't seen this on my machine, at least not
flipping between a full-screen DOS box and the Win95 screen.  What
video mode do you find exhibits this problem?  After reading your
message, I tried a variety of 256-color SVGA resolutions, but couldn't
get Win95 to flake out in that way.  One thing it never does correctly
is to restore the border color in the DOS screen if you've changed
it; there may well be other things that don't get saved and restored
either.  And I do find that flipping between two DOS boxes can cause
the problem you mentioned.
