    Using mouse in a VM makes top menubar go crazy since Mountain Lion upgrade

    avanpelt Novice

      I've been using Fusion 4.1.3 and Mountain Lion together for about three hours now.  I can run a VM, but when I do strange things happen in the Mac environment.


      One of the first things I noticed was that when I move the mouse inside the VM, the top menubar (File, Edit, View, etc.) on the Mac side goes crazy like it's hyper-cycling through the other open programs on the Mac side.


      Also, if I do a Command-Tab to cycle between open programs on the Mac side, the switcher flickers on the screen and sometimes won't disappear until I quit VMware Fusion completely.


      Note that I'm observing all of this happening on my primary laptop screen while working inside a Windows 7 VM on an external monitor.  Also, open windows like Chrome and Safari on my main laptop screen jump up and down slightly when I'm moving the mouse inside the VM on the external monitor.  I'm guessing Apple must have released new graphics card drivers with Mountain Lion and Fusion 4.1.3 isn't optimized for them.


      I am running Mountain Lion and VMware Fusion 4.1.3 on an early-2011 i7 MacBook Pro with 8 GB of RAM.


      Anyone else seeing these problems?  I hope 4.1.4 is released in fairly short order.
