			   SCREEN REFRESH ON ADVANTAGE! NOTEBOOK


PROBLEM 
When running an application written in FoxPro for DOS on the Advantage 
notebook, the screen information is either blank or retained from the prior 
screen.  Random characters are left on the screen as drop-down menus are 
moved from one side to the other.

CAUSE 
The MS-DOS disk-caching program SMARTDRV.EXE is incompatible with FoxPro for 
DOS running on the Advantage! notebook.  Any implementation of SMARTDRV.EXE 
will cause screen corruption in these applications.
