Here’s the version with those lines commented out and setting the preferred size so that the progress bar doesn’t end up as 0,0,0 in size:

Sorry you were having so much trouble with this. It really shouldn’t have been this difficult. :-/
If you roll your own GUI you might still consider using the picking stuff from Lemur. It can be used without the other stuff.
