I recently installed parallels 10, with windows 8.1 onto my Mac. Everything seems up to date and working. Except if I enter coherence mode the "desktop" version of windows 8.1 does not actually work. If I use the "new" block type, it works fine just like launch pad. But when I try and switch to "desktop" it will not do the coherence properly and just basically doesn't show that there is any interactions going on. Anyone??
