I am able to get this to work with my Perforce setup, however there is no easy way to make the History Diff window full screen. I am forced to drag the edges/corners of the window to resize it. Standard double-clicking of the top bar doesn't allow to snap to full screen either. Also there is no button in the top right corner to make full screen as most windows have.
I am using Windows 7 64bit.
Is there a way to make this possible?
