If you edit a file using joe and then split the screen, the
top window will scroll down without any problems. Scrolling
up, however, it does not, you have to refresh the screen to
get it to display properly. Also, sometimes when you cut
and paste, you have to refresh the screen to see the changes
This has been assigned to a developer for further review.
I cannot duplicate this behaviour under gnome-terminals or xterms
using Joe 2.8 in the latest tree. If it was a ncurses problem (most
likely), it appears to have been fixed by newer versions of the curses
libraries than shipped with 5.1.
