That's a reason I am trying to agree our users to use "ROOT" first
(at least as a tool to create a prototype).

I've looked at your code and just found what I DID expect to see!!!
Did you understand what the line:
cerr << "starting the application" << endl;
theApp->Run();
is done for ???
One may manipulate with the "mouse" only from WITHIN
theApp->Run()
Just you leave TApplication::Run() you lose any mouse control.
When user loads his own DLL from Cint command prompt it is always
the case, since very Run() method calls someway YOUR methods but
remains always within the ROOT event loop.
Well, one may restore the mouse control but for that one needs
to enter the ROOT event loop again.
Namely call theApp->Run() for the second (third , etc) times.
Please look up our Test/HWORLD.cxx example carefully and find
in there the second call.
But I am repeating it would be better to make ROOT DLL. Why you
don't like this.
Just load your TdcMenu via ROOT and perform the rest part with
either ROOT macro or with another DLL (share lib).
I am really interested why you found this way non acceptable for
you.
With my regards,
Valery
