I have two monitors (both 19"), using the primary monitor for Snow Leopard 10.6.3 and the secondary one for my Windows XP Pro Desktop. When I move the guest OS window from my primary monitor to its permanent location on the second monitor, the guest OS system's window overflows the screen on the sides. This means that to close a program, etc. using the top menu button is impossible without moving the window to the left. I prefer the Window mode to Coherence. The vertical screen Desktop image is fine, with the bottom tool bar visible. I've read the manual and searched on this site for an answer, finding nothing. I need to have the guest OS window fill the second monitor, but NOT overlap both sides. What do I do to make the desktop window fit the screen properly? Toby
