I've been using Parallels for a while on a Mac Retina. I created a Windows 7 instance which is where I do a lot of my work. I also created a Windows 8 instance to be able to play with it and see how it does. It's now about 9 months later and I recently ran the last Parallels update. Coincidence or not, what has started happening is the wrong version of instance of Parallels is opening when reading mail and open attachments. Actually, that's where I see it most but if I have a Word or Excel file and open it, it would always open Word or Excel in Windows 7 which is the only place I have those programs. But now, it always opens the Windows 8 session instead and, of course, nothing happens because the software isn't installed. Just a waste of time waiting for the instance to start so I can shut it back down. How to I define what is suppose to be opening and how did it get changed? Thanks.
