player exits full screen every 10 minutes

What settings do i need to stop the player from exitng full screen every ten minutes?I run on Vista

You are probably going to have to describe what you mean better than that.

When i play a movie,and put it on full screen,every ten minutes,it goes out of full screen mode.Im playing them on my 42" Toshiba.Ive set my computer to no screensaver,no power management,to never go to sleep or hibernate mode.My tv is not set to go to sleep either. If that`s not enough info,please let me know what it is you need to know.Thanks

When the computer pops out of full-screen mode, it’s typically because something else is trying to display a notice, something that can’t support the current display mode in order to pop up in that mode. You should check what other software is running that would generate interruptions at the intervals you are seeing.

Solved.You were right,it was another program trying to connect.(Weather Network)I was not connected to the internet,so the program tried to connect every ten minutes.Thanks
