Dragging any guest windows (Win7 x32) are lagging behind mouse. I know this is not a good measurement but on 4.1.x is was much much faster. Also dragging window around leaves dirty lines (from dragged window) on desktop all over. At some point it desktop will get refreshed. I try to get screenshot but whenever I try to get screenshot desktop is refreshed. When I mean drag window in circle motion mouse stops and window still is in motion following circle. I did try to uninstall guest tools. Reboot Guest and Host and nothing works. Host is Mt Lion 10.8.1",defect,new,other,VirtualBox 4.2.0,,,,Windows,Mac OS X
