Hi Tim,
can you tell us in which situation stable (1.0.2?) crashes? Seems we
missed to backport a fix.

Thanks Tim for contributing this fix. IFAIR I did some debugging about
this myself, can't remember what happened.
We'll be upgrading our wx snapshot quite soon (as soon as I find the
time to do so, yes guys I'm telling this for quite a while now...), the
2.5.1 release is settling these days. The Scintilla control has been
updated, and AFAIK there has been work on focus code too. Maybe the
problem is already fixed properly, if not we'll certainly incorporate
this hack into our version.
