Hi there!!!

Are you still having troubles with the screen size??

Can you go to the Desktop, right click in a free area, from the menu that appears left click on PROPERTIES then LEFT CLICK on SETTINGS from there look at the "SCREEN RESOLUTION" - If it says it is set for anything other than 800x600 slide the lil dohickey thing over to 800x600 - click OK - expect the screen to flicker and then CLICK YES when shown a new window - Let me know if this does the trick
