pq06439.st  IN MULTI SELECT LIST ALL ITEMS LISTED ARE NOT BEING SELECTED PROPERLY

Create a multi select list with 3 items, connect aboutToOpenWidget      
to a script with item 2 and item 3 are being selected (selectedItems:)  
To test, multi select list with item 2 and 3 are being selected         
appearing, to verify, inspect <<self testMSL selectedItems >>,         
then select items 1 and 2 by swiping them (do not reclick the mouse),   
then inspect << self testMSL selectedItems again >>.  Widget            
still thinks item 2 and 3 are selected..
