Thanks for the input Stan. What I ended up doing was pad each .add 
string with spaces and it alleviates the problem. I also resized the 
list horizontally to 160 so it fits the entire width of the screen 
and now the scroll arrows seem to work. The width doesn't really 
matter with this particular project. I have seen what you mentioned 
regarding the vertical size a while ago.

match what yo're describing when I had graphically resized a list 
larger (vertically) in NSB, but without increasing the number of 
visible items in the list. I had about 1/2 line extra, and I would 
get left over garbage there after scrolling. This can be avoided by 
making your list smaller in NSB, then setting the number of items in 
the list to the number you desire. NSB will then automatically size 
the list vertically for you, and it will work fine.
