I guess you are calling a COM method and therefore the original app waits until the whole method returns.

Since the form should be in a COM exe, it should have it's own thread.
So basically the question is to start and later synch again. Sionce it already is implemented as COM, I'ld try starting the COM-Form via timer, which is enabled in the method called by the original process. Another sometimes easier way is to have timers in both apps and only set certain flags while communicating and checking those flags in the next timer firing sequence. This returns quickly (so you can work in the original process' thread again) and starts off the second form in the next timer interval.

From tabula rasa I'ld implement it as simply another exe which communicates, but I don't have enough info about other needs of your app to second-guess.
