With PKEEP, the brw should redraw at the same position in the data, so 
"how many down" would always equal 1.

You could keep a list of previously-selected items (in an array, a temp 
file, etc.) and DROP them when drawing the browse.  If you really need 
to show them but simply not have the brw lu cursor stop there, you want 
John Esak's extremely clever "pig in a poke" technique, which allows 
enormously enhanced program control over browse lookups and is useful 
for all manner of cool things.  John was selling this on the list for a 
few bucks several years ago, you might want to contact him.
