Hi,
I don't know why this is; perhaps you can put a breakpoint in the Mac
code that processes button up events: see src/mac/carbon/toplevel.cpp.
However some implementations have trouble with intercepting events for
(and drawing on) frames, so usually having at least one window in the
frame client area is recommended. If things still didn't work properly
with that window, then I'd be concerned.
Regards,
Julian
