Re: [paragui-users] Bug in event handling?

[Alexander Pipelka]

Sorry,...
This one was (is?) a really nasty one. I've been investigating into this
quite a long time. The problem was when an object is deleted the
iterator of the objectlist gets invalidated. I also found some other
problems related to STL vectors i haven't solved yet.

At least this bug (to be precise: the symptom) is fixed now.
