Good news.  I look forward to the new version.

I've also noticed that if you scroll the screen, a CR goes to the line
after the screen instead of the last line in the screen buffer.   As a
result, new text overwrites old text.

My memory is that the pre-cygwin version of tcsh, restored the screen
as it was prior to the scroll.

As a convenience, I think the 'escape' key should similarly restore the screen,
