I uses Parallels 7 and there are two guest OS installed in Parallels Desktop (Windows 7, Mac OS 10.7). When I load the Mac OS (as a guest os), there is no titlebar in the windows. And There is a black space at the bottom of the window. (A screenshot is attached along with this post) And the co-ordinate of the mouse cursor is off the exact location. I try to click point A (x=100,y=100) but the system accepts it as (x=100,y=~70).I have to click ~30 pixel below from what I intend to click.
