Okay, I can replicate that. I'll look into it. Thanks!

Fixed in r669.

The problem was that I was faking out Synth's region/style calculations for the 
internal frame title pane by 
having a static internal frame that I would substitute for the parent when 
doing the comparisons. This doesn't 
work if the UI has been assigned on the command line because the UI hasn't been 
initialized when the 
internal frame is created.

I could have fixed this by assigning the static FAKE_INTERNAL_FRAME when it is 
first needed, but I decided to 
simply test if the region pattern is looking for an internal frame and 
reporting one found.
