It has been ages since Apple squandered all their
good will with me, but I can't believe this little
box doesn't come up by default. Are you sure you
are not doing something in your code to prevent it?
Applying the TLB_FRAME_ATTR keyword will prevent these
kinds of things on Windows platforms. I'd look for that
keyword in your code.
