issues with nano via ssh

We're using nano from the AIX Toolbox (installed with yum) via ssh. Scrolling is really bad with it. Am wondering if the problem is a setting with the various ssh clients we're using or termcap/terminfo or with the build of nano. Debating whether I should rebuild nano from source or if that's a waste of time. Anyone else having a similar issue? Any recommendations on how to fix scrolling? Thanks.
