Hi David,

thanks for your answer.

Not a problem at all, this wasn't very urgent -- I just sent the email
as a friendly reminder, since I assumed most people don't routinely
look through emails which are older than two months.
It is invaluable to have someone as familiar with the API as you are
answer tricky questions, no matter if it takes a few weeks now and

The solution you suggested did indeed fix the crashes -- cool! Now I
can finally merge this nice feature :)
I was always confused about that m_dynamic parameter -- I assumed the
default value taken from that member function would do the same as
passing m_dynamic. Turns out this is not the case.
And yeah, UnsureType is indeed a good example, I'll look at it next
time I have such a problem.
