Well, that would be fine. I don't need to get the text, if there isn't
any there. But how can my hack determine whether there is a custom
menuitem draw routine, in order to know to not call LstGetSelText?
I had assumed, incorrectly, that the OS would simply return zero
in that case, instead of just crashing.
I wonder if I should test for a non-zero listPtr->drawItemsCallback,
and if so, then skip the call to LstGetSelectionText......
thanks for the info
