Im on ubuntu 10.4 with a win7 Guest.
If the workstation window has focus, the guest will not grab focus when you run the mouse over it. I have to put the focus on a different window or just click on the ubuntu desktop and then the workstation will grab focus when I mouse over it. This started about a week ago and I can not think of anything that changed.
VMware tools installed?
Yes. I also just upgraded from 7.1.3 to 7.1.4 but that did not help. Also when I am in the guest and I pull up a window in front of it on the host, it no longer releases the mouse.
