I don't recall having this problem when running Open/Matchbox, but I may have over-looked it.
For reference sake I think I "ipk install aterm" got the package from the Beta3 feed at tyrannozarus.
When using Aterm under R198 and EvilWM navigating around folders and doing general stuff works fine, but when I try and use vi I've noticed two thingsH
-I can't get to the point where I can run commands (i.e. by pressing the colon key)
-When I scroll down the text file I can't scroll back up.
