This sounds similar to issue 180
(http://code.google.com/p/texworks/issues/detail?id=180) which was never
followed up on, however.
This seems to be some kind of problem with the keyboard focus. Normally,
the editor widget should only receive key events if it has the focus,
and should loose this focus if you navigate to the menubar. As it still
receives key events, apparently this never happens or is not processed
correctly.

Since I have neither any experience with Mac nor access to one, I can't
test any ideas and therefor can't help with any bug fixes here. But if
someone who managed to build Tw on Mac is willing to try a few things, I
could give some ideas.

Regards,
Stefan

PS: Some Qt menubar issues on the mac have recently been fixed
(http://bugreports.qt.nokia.com/browse/QTBUG-8698). I have no idea if
they are related to this issue, though.
