selectedText confusion

[Graham Samuel]

I've got a list field where one line is hilited (I can see the hilite), and 
I have the following handler in it

on mouseUp
   global lcgCurrentPerson
   put the selectedText into lcgCurrentPerson
end mouseUp

I send a mouseUp from a handler in the stack which owns the field in order 
to fill my variable lcgCurrentPerson, but all I get is empty. Can anyone 
explain this?

(RR2.2RC on Windows XP Home Edition)

TIA

Graham
