Try playing with pulldown menus (especially move between them).
I can upload some screenshots with corrupted screen. I may also upload
my binaries, maybe i just have made something wrong.

Yes. People who have 6.2.1 PE beta and 6.1.0(a) have the same problem.

PR> I don't understand anything. What is "y"?
"y" is the number of row on the screen. That's why I thought the
problem is in setting the cursor position.

I just do not know how to reproduce it. But everyone who has binaries
made by me, see that problem. I have tried to reproduce it outside of
mc, but had no luck.

Ok, I'll try that.

I just thought this patch might have broken something. I do not
remember those bugs when the screen was coloured red ;) Maybe I am
