I just upgraded to PD8 and am experiencing a problem with my mouse pointer disappearing when switching between an OSX window and a Windows app in Coherence Mode. For instance, I am running Microsoft OneNote next to a Safari window, and after browsing in Safari, my mouse pointer disappears and only becomes visible again when I click something in OSX. I have reinstalled Parallels Tools successfully, which seemed to temporarily remedy this problem, but this issue has since returned. Very, very frustrated with the upgrade right now. I am running PD8 in Mountain Lion, and am running Windows 7 Home Premium. I appreciate any help I can get with this.
