Strange behaviour of Scenarist simulation window?

[Fotis_Greece]

Everything works ok with my projects but when I try to use this simulation window and I click the play button the actual video opens in a new little window within the simulation window which has the name "object design" and I have to click on it in the windows XP toolbar to see it.
Actually every operation I try to do in the simulation window results in opening this annoying "object design" window.

Has anyone else seen this bug, or it's only me?

Yes, I will second that! I have been having this problem for a while now on both 3.1 and 4.1. It doesn't happen all the time but often enough to be very annoying. I have no idea what might be causing it. Anyone have a clue?
