I don't know if this is the problem, but I think you just have to uncheck the "Enable full screen skin" under Skins Preferences (Right-click -> Options -> Preferences -> Skins).
For Pleuris's problem I don't have a solution, try moving the mouse away the player's window and wait.. or make a search in this forum, in previous BSplayer releases there was a problem with the Hide mouse pointer feature..
Hope this could help! :)
Bye
