Let's see if this is an idiot question: Installed Parallels on OSX, created a VM from my Bootcamp partition, and now Windows wants me to approve the installation of the Parallels Tools, among them MicrosoftPS/2 Mouse driver. Now, as soon as I click within the Windows window, the mouse cursor disappears and can't be seen until I press Ctrl+Alt to release the mouse and keyboard. Can't use TAB/return either to press the OK button. Sort of Catch 22. Can someone help me?
