You have to methodically determine on an event by event basis what is 
going to cause selection and what isn't, then update the menus 
accordingly. It takes a lot of testing. An alternative is polling 
whether text is selected at the moment but is a waste of CPU cycles and 
is unnecessary.

Best is to let the system clipboard handle copy-paste as it was designed 
to do. You are opening a can of worms trying to micromanage your 
application.
