I just set up a brand new Windows 7 Dell computer for a friend and install DOSBOX because he wants to use an DOS database program.

The program works fine in normal size (small box), but run full screen either by entering ALT+ENTER or changing the config file to fullscreen, NEITHER the mouse nor the keyboard works!

This is a standard Dell wired optical mouse and wired Dell keyboard.

Any ideas? My friend cannot see the small box and font in default mode.

Thanks,
Edgar
