Hi, This was all working (installed yesterday) until this morning, when the guest OS decided to just display a black screen. NB The mini-screen in the Virtual Console looks correct. Also if I drag the window size, the screen is displayed during drag but reverts to black when I 'let go'. I can right-click on the desktop and the popup appears on the console (not client window). I guess its a display problem - HP/Compaq nx6125 notebook, AMD Turion 1800M, 1.5 GB RAM. Host is XP-SP2 patched up. Guest is XP-SP2 patched up as of yesterday. Makes the system a little unusable right now :-(. Thanks for any assistance.... Regards Graham
