I am running the latest version of Parallels 7 along with Windows 7 on a Macbook Pro 15.4", Mid-2009. I am on Mac OS X 10.7.3 11D50b (latest version). I have an Apple CinemaDisplay monitor connected to my Macbook which I use as a second monitor. I have dedicated 64MB video and 4GB RAM to the VM (I have 8GB RAM total on my Mac). When I run Windows 7 in coherence mode and try to maximize a Windows 7 window on the second screen (the Macbook display), the entire window, particularly around the edges most of the time, does not fully repaint on the screen, if that makes any sense. Basically I can see the window behind the Windows 7 window that I just maximized, "bleed through" in a sense. If I click anywhere on the window the Windows 7 window in that particular section appears at the forefront. It is like the screen is not refreshing or something. If I un-maximize the window on the second display it works fine. Very strange! When I run Parallels in full screen mode both screens work fine even when the window on the second display is maximized; also when in Coherence mode when I maximize the Windows 7 window on the primary screen it works fine. Anyone else have this issue?
