When you use this drawing technique, you also need to handle the popSelect
event to run your own logic to set the desired label into the popup trigger.
Then return true from the popSelect handler to prevent the OS from trying to
do its default behavior...
...which is to just grab the text for the selected item from the array of
strings that you originally passed to LstSetListChoices. But in this case,
you passed NULL for that, and the OS doesn't know any better, so it crashes
when trying to use that NULL pointer.
