Dave Ewart <davee@ceu.ox.ac.uk> reported sluggish performance in the
Stata 11 Data Editor when using it from their Linux server via X11 
forwarding.  First Dave should verify that the latest Stata updates 
have been installed.  Next he should open the Data Editor, access the
"Preferences" from the "Edit" menu, and then check the box labeled 
"Disable visual gradients (improves performance)".  This option was 
added specifically to improve performance when using X11 forwarding.
