I'm not in a position to test this, but I will comment that if you
mark the radio button for a different config.sys / autoexec.bat, then
Win95 will do a warm boot before loading the program.  There may be a
problem running win /b after that.  (win /b is what restores your old
config.sys and autoexec.bat, and then reboots the computer again after
your program has finished.  It is automatically placed at the end of
autoexec.bat in the per-program version.)

Happy hacking,
