No, it doesn't reset, it uses the same data each time it is opened. I  
put the code in the openCard handler, but you suggested the  
preOpenCard call, it works ok in openCard, but would it be better to  
put it in preOpenCard? I thought that a card might have to be  
displayed before the selection would appear. By selection I mean the  
mark that appears when you do:

set the hilitedLine of me to the cpSelected selected line of me

Thanks a lot
