Geoff told me ,three months ago, that he was working ,among many other things,on such a device.

I had the same problem, when I tried to make it.I found later in the PC Bible (a book written by Michael TISCHER) a TSR source. It saves the screen content before displaying something. But I had to stop my investigations and until now, I had no time to test it. I also thought about testing the file existence every XX keystrokes ... > >Has anyone already written something like this, if you haven't but >have thought about what conclusions did you reach. > >Any help would be appreciated.
