 This does seem to confirm my idea that we're somehow ending up showing the
dialog from inside wxYield() call. As calling wxSafeYield() from inside
wxYield() does nothing (which was considered to be "safer" than yielding
recursively and crashing with stack overflow), this could explain the
observed symptoms. I still don't see how can we end up inside wxYield() in
the first place though... Had you done something else before seeing this
problem? I suspect that the real bug must be elsewhere, and this is just a
consequence of it, but it's nothing more than a suspicion unfortunately.
But if you could remember which operations you had performed before seeing
the bug, it might provide a way of reproducing it.

 Thanks in advance,
