slow COM

Hello,

I developed a Windows Form Control, and put a COM wrapper around it.  The
control runs correctly on my development machine, but when I deploy it to
other machines (using VS Setup utility), some of the functions in the control
take up to 3 minutes to return (I found the functions by writing to a text
file at entry and exit times).  An example of such a functions is the
ListBox.SetSelected(...) method - it took over 3 minutes to return.  I am
starting to think that maybe the slow run time is because of some kind of
incorrect interop functionality has anyone else ever encountered such a
problem?  Anyone has suggestions?

PS.  I know that this is a public domain and some might not want their
answers to be scrutinized by the whole community, but I really need help - so
if you even think that you know what's going on, please email me at livshitz
on the domain purdue, extension edu.

Thanks in advance,
Yuri

It's not clear what you have done:

- a .NET UserControl registered as an ActiveX control
- a COM control (non visual) that opens a new Windows.Form

Supposing it's an ActiveX control: what's the host for
the control? The framework supports only MFS 7.1 and IE containers.

bye
Rob
