I am running Windows 8.1 in Parallels Desktop on my Mac and have been doing so for over two years without a problem. Suddenly, when I am using Windows, I am no longer able to access any of the Mac software such as Google Chrome, Outlook etc. When I click on them, they just appear as a ghost image on the screen, barely visible underneath the Windows home screen, and not able to be used (as shown in the attached screenshot). So now, if I want to go to a website or look at my emails, I have to close Parallels. Is there any help for this, please? Thank you.
