Hi guys,
After some hours spent on research and test, I have found some ways to workaround that issue.
Invisible mouse is a problem that affect some physical desktops with Windows 7.
In my case, the cursor disappeared only after unlock (login session) windows 7 virtual desktop if all apps were minimized. To mouse pointer become visible again, you had to open some app or window.
I have two Workarounds to View 4.6:
#1. Enable mouse trail and set it to be as short as possible. With it, the cursor will not disappear again, but the user expirience is affected.
#2. Change video driver from SVGA 3D (WDDM) to SVGA II. That's totally transparent to users and the mouse pointer will not disappear again. The counterpart is that VMware does not recommend that driver to Windows 7.
How I solved:
After migrate to View 5, vSphere 5 (vcenter and esxi + patch ESXi500-201109001) , upgrade VMware Tools and virtual hardware (v8), but maintaining view agent 4.6, the problem persist.
After update view agent to version 5 finally the problem is gone!
Hope it help you!
