This depends on Windows, not Allegro or djgpp. Tabbing works fine on 
probably 99% of machines, but you may have problems depending on your 
video driver and DOS box properties. You are actually lucky that it 
just refuses to let you tab away from the program: more often, Windows 
will switch away quite happily but then crash when you try to tab back 
to it :-)

You may be able to improve things by tweaking your property settings 
for the program in question, but it sounds to me like your video 
driver just isn't able to store the DOS graphics state correctly, 
and there isn't anything that you can do to fix this.
