I downloaded mark and tsr-rem to clear TSR programs. On my own computer, if I boot with my pure DOS 6.20 boot disk, they can be used, but when I take them to another server they won't run properly (well, it's not exactly that they won't run, but when they run no text is displayed, and the cursor jumps from the bottom to the top, so the TSR program can't be ended). Why is this? I'd appreciate everyone's advice.
