Since MMF2 (And MMF1. is MDI, I see no point having more than 1 MMF2 window opened. In fact, it's pretty annoying.
I believe you all download examples or double click an MFA file but it opens in a new MMF2 window.
Sometimes I even get to 4 MMF2 windows opened at once, which is a real pain.
My suggestion is making the MFA files open in an exist MMF2 window, if there is one opened, instead of opening a new MMF2 window every time.
Can this be implemented?
