I just upgraded to 1.45 from a few versions ago (1.41 or 2), and my UI disappeared.
The plugin opens, sounds ok (for a work-in-progress), but the only thing showing is the text boxes for sliders, and those are blank.
There’s no sign of life (mouse-over) where the controls are supposed to be.
It’s fine in Debug mode, just not in Release, where such problems are of course harder to track.
It happens with the regular look and feel class as well as my custom one (which wasn’t based on shiny anyway, so that shouldn’t be the problem).
