Sony vegas pro 11 pop-up windows issue

Basicly, all my effects in video FX and compositing mode etc should come up over sony vegas as a pop up window. But now I only see the window like pop downwards and never actually popup infront of the main window. I tried to reset to default layout etc but didnt seem to do any difference. Also tried hiding toolbar, couldn't find the popup.¨

Where could it be and how should I find it?
