When you change the list choices, explicitly reset the label in the popup trigger using CtlSetLabel -- this control doesn't have a copy of the label string, it actually points to the string that was contained in the list and now has been replaced.When the user selects an item from another list on the form, I need to repopulate the list control with a new list. I do this in the popSelectEvent of the first list. So when this happens, I free the ListStr[] pointers, then repopulate it with a new set of strings, and call LstSetListChoices and LstSetHeight again with the new values. This works fine for a few times, but then I eventually get an error is POSE that it is reading from an unallocated chunk of memory. What it appears to be doing when the error happens is refreshing the label in the trigger control from the old ListStr[] pointer which of course no longer exists. I can't seem to track what it is exactly doing but it is not happening in my code anywhere.
