[Help-nano] Nano scrolling only refreshes half of the window

[Nick Shaff]

Hello,

I seem to be running into an odd issue recently with nano that's come seemingly 
out of the blue. If I open a longer file and try to scroll down through it by 
moving the cursor with the arrow keys it only visually refreshes the bottom 
half of the window. Oddly paging through the file with ctrl-v and ctrl-y still 
works fine, but I can't seem to figure out what caused this recent problem.

I'm running Mac OS X 10.6, and was running the default nano installation 
(2.0.6) with the default configuration (set nowrap). I tried compiling and 
running the latest version of nano and that didn't change anything. I did 
install python (2.6) and pyreadline recently which was suggested to me may be 
linked to the problem, but I honestly cant remember if this behaviour was 
happening before then or not.

In any case any help or suggestions as to something to try would be greatly 
appreciated. Thank you.
