Yes, in old versions of lp5250d it was easy to overflow the buffers
created to store the output command, etc.  (I used to manually patch
lp5250d every time I refreshed it from the servers to fix that problem)

This, however, was fixed when I changed lp5250d to use the new config
file scheme. (Instead of the command line switch scheme)  From the
examples that you're listing here, you're using an old version.  Please
update to something newer, it should solve that problem.

Hmmm... I haven't run across that one...  Sounds like maybe a key is
getting stuck, from your description?  I guess what I'd do (to try to
narrow the problem down) is exit tn5250 when the cursor is going nuts, and 
see if you have the same problem in other apps.
