Can't go fullscreen?

I'm using the epsxe emulator, and the window can't fullscreen. It doesn't have a title bar, so I can't just hit the fullscreen button.

I also tried both the Alt+Spacebar+M and holding shift and right-clicking the tab to hit the Move option, but once the move cursor came up, I couldn't drag the window for some reason. I would try, but the window wouldn't move, and after I let go, the move cursor disappeared and went back to the normal cursor.

Is there some other way I can get the window to fullscreen?

Have you tried pressing Alt+Enter?
