Well, I suppose it reentered DOS (that is, DOS-C) at the wrong time. It checks whether a key was pressed on hardware interrupt 08h (Timer) instead of Int09 (Keycode send), probably because too many programs overwrite Int09 so that won't be reliable. The major problem of this is that it doesn't check InDOS (flag that shows if DOS is busy) and then might call DOS when it isn't ready. I don't know why this weird method works fine in MS-DOS though. Does the crash always occur? Does it show rather random characters or are they always the same? Which application do you abort?
