I had a short correspondance with Chris about the "scrambling" too. I am
running (sometimes) Yarn95 under NT (both 3.51 and 4B2).

What I found out was that if I set the buffer size to be the same number
of lines as the window size (eg. 80x60) the "scrambling" disappears.
Previously, when I had the buffer set to 200 so that I could scroll the
window it scrambled everytime there was a screen update.

Could this be your problem?
