More Data: I have my security settings allowing only app store applications and signed developer applications, the mouse tracking return just after enabling ALL Applications to be able to run the VirtualBox Uninstaller, after reboot I return to my std settings allowing only signed apps.
This bug its an major headache at Apple comunity nowadays, I posted the solution there too.
Sorry if I dont post on the bug tracker, I'm not familiar with this community, neither have enough spare time too.
Thanks
