286 Xenix Hercules Scrolling Problem (help!)

[Jon McCown]

I just installed 286 Xenix (Tandy labeled Microsoft product) and have found
a bizarre problem to wit:

System:  Herc Clone Mono Video, Mono Monitor, 286-12, 2MB Ram, MFM disk etc...

Once the screen fills and gets to the bottom line (ie it should scroll up),
the screen scrolls, but no further text is output.  (invisible text? :-)
After a while of pounding return, text will begin to appear at about column 40,
but it is not 'current' (seems to match what should have appeared earlier).

My guess is that the invisible text is being scrolled up through the video
memory above the visible area.  I have seen a similar problem with PC/IX
where displayed lines 'reappear' at about column 40 from time to time.

Is this a known problem (ie got a fix?).  My apologies for running an old
release of Xenix, but the price was right.

- Jon
