I open Fusion in a window on my iMac and start up Windows 7. The cursor works normally within the window, but if I try and move it out of the window, it freezes. I then have to Cmd-Tab into a different window to work there, or move the cursor back into where the Fusion window was and then Cmd-Tab back to Fusion, then I can carry on working.
It happened occasionally when running Fusion 5, but not every time. It still happened after I upgraded to Fusion 6. I hoped an upgrade from OS10 10.8 to 10.9 Mavericks might help, but it made no difference. It seems to happening more frequently and is getting quite annoying. Has anyone else come across this and found an answer?
