I have bought new notebook, Windows 7 Professional after learning from Autodesk technical support that Architecture 2008 will work only in Virtual Environment of Windows XP Mode. I have installed ADT 2006, Arch 2007 and Arch 2008 within the Virtual Environment with no problem. I have been able to open previous drawing files with no problem. It seem to be smoothy until... croppy drawing lines, croppy installing door and windows, etc. That is because of lagging mouse movement. That can affect productiability, So I wonder will anyone know of solution to this mouse-related problem in Windows XP Mode environment?
