Well I'll try a coupla things...

1) Maybe PEMSTATUS should be checking 4 instead of 5?
--- You could really get by without the PEMSTATUS I think.
2) Maybe ADDPROPERTY() would make a difference?

good luck

>>Why does the screen clear? It does the same thing even with no change to the screen in between the two procedures...it always appears to occur when the screen is unlocked in the screenrset procedure.
