I just committed a fix for this because I was able to reproduce it. You
can optionally pass a wxWindow to wxSafeYield to prevent it from
disabling input from that one window, which is what I have done to allow
the cancel button to be pressed.

I'm not entirely sure why we don't just use wxYield here and allow the
rest of the UI to be usable as well - is there a reason for that
Andreas, or is this just an oversight?
