Fullscreen no video, Moviemode works fine

[BSplayah]

Sup guys, just signed up to ask a question, because my BSplayer is all messed up since yesterday.

I start a movie in windowed mode and when I double click or press F for fullscreen the video goes black and stays that way until I close down the player. If instead I enter movie mode (what's the difference anyway?) I can watch it in fullscreen np.

Why is this happening and how do I get it back to how it was before?

I've updated to the latest version but the same thing still happens.
