I also seem to remember reading in the manual that Desqview will
not spend multitasking time on a program that is waiting for
keyboard input only.  If this is the case, then it might be
better to allow them to run.  That way, if they do have something
to do, they can, but they normally wouldn't, such as my Microsoft
Word.

This has not been my experience.  This particular program is the
public domain terminal emulator from NCSA.  It is controlling an
"ethernet" card.  Programs like "Switch-It", that swap out tasks,
will cause the connection to the cluster server (a Unix
workstation in this case) to be lost.  I believe that there is
either a keep-alive response that is required periodically, or
else switching out the task drops some line on the interface
card.
     If you are running a downloading program only, things may be
different.

Thanks for your reply.
