Here is a part of the code. I included only main parts which deal with
this issue. I hope it will give you a picture what I'm trying to do.
The part which takes long time is "m_Tcl.brExecut e(oMs,oMs);"
Question for Willy:
You mentioned to run the thread in an STA. Could you please send me
some sample of this?
Thanks
Paul

Make sure your separate thread is initialized to run in an STA, if you
don't, your COM object will still run on the UI (STA)thread.
Also note that you shouldn't directly update the UI elements from this
thread, you have to call Control.Invoke or Control.BeginIn voke.
