Hi Mike, Unfortunately I don't have an OSX box or much experience with Qt to contribute to resolving this issue, hopefully others might be able to help, but the combination of Qt+OSX is likely to be quite niche so it might something you'll need to spearhead.
As a general comment that might help the process of characterizing the bug, does the same problem appear on other OS's? Does it appear on other versions of Qt? I do wonder if the newly released Qt5 might have changed things under OSX - possible for better or worse! Robert.
