I'm not sure if you're having the same problem I found or not. Does
you're dos work find under a virtual console? I have configured my
dosemu to use graphics (usually from a virtual terminal), but when I
run it under X it works fine as long as I don't display ANY VGA
graphics. Since I'm booting the command line mode of Win95 I get the
windows Splash screen and that will cause it to die.

My solution is like your's. When I run dosemu from X I hit ESC in the
window before it has a change to display graphics. I can then run
Quicken for dos without any problems. Although if I tried to display
a graph it would die.

If this sounds like what you're seeing. Then I would suggest you
remove the graphics capabilities from dosemu.conf or use dosemu from a
virtual console. Anybody know a better way around this?
