Hello, it does seem to me that all ti89 programmers hate horizzontal scrollbars (whenever it is possible).
I know this doesn't really compete to you since WordRider is not a text/image viewer, however I found it very annoying to have all my text and image compressed into that small column. I can't even view larger images(this is actually my problem) since they get cut to fit in the layout. I tried for hours and hours to find a workaround for this but whithout success.
I think WordRider could be used in a much more powerful way if it could be implemented with a reader/viewer with horizontal scrollbars to be installed on ti89.
This is my suggestion ;)
Bye!
