No, I think it is not ICS related yet, I just wanted this to be stable
*before* putting much code of ICS into it. I don't want to make the same
mistake as in the first run. Build it step by step now and test after
each step.

Okay, but I thought it could block events, but as they're triggered by
windows messages anyway any timers or ICS components etc. which use
events will be triggered then and run fine I assume.

Yes and no. If the program simply fails I don't want to have to restart
the whole PC just because of that. The dll should terminate all
connections gracefully then so that you just need to restart the failed
app. again and all is okay.

Hm, but it the thread is to be created only once, it's a problem if it
is created from initialize. Okay, as somebody else already told me I
shouldn't create the thread from initialize anyway. If I have changed
that I won't be a problem anyway.
