There does seem to be a problem with the Windows console. I have 64 bit
Windows 7, and when a console window height*width is bigger than about
16384, it starts clearing the window after "less". This is running
"less" from the Windows shell. Not only does it clear the screen, it
clears it to black, even though I have a different background color.

With mintty and bash it works for me at least up to 383 rows and 1364
columns.
