Stu,

Your intent was clear, but your code will call HandleEvents 999 out  
of 1000 loops!
I think you meant         if myCount MOD 1000 == 0 THEN HandleEvents

MOD is a relatively slow operator to use in every loop, so I would  
probably choose something like this:

IF myCount >= 1000 THEN myCount = 0 : HANDLEEVENTS

Another cute method, definitely not RP-approved, calls handleevents  
every 256 loops:

DIM myCount AS BYTE

DO
       ...
       myCount++ : IF myCount == 0 THEN HANDLEEVENTS
       ...
UNTIL done

Do you see how it works? :-)

   e-e
   =J= a  y
