Not sure if this is only a Mountain Lion issues but have tried to play some content that required Silverlight on Microsoft's web site and it plays for a minute or less then freezes. I am running latest Parallels 7 with Mountain Lion on 2011 Macbook Pro. I did not run parallels for a while when I was testing Mountain Lion. I have just recently gone back to running Windows 7 through Parallels. Seems fast enough but have had plenty of minor annoyances. Such as Coherance mode display issues where start menu disappears, random crashes of IE 9 and sometimes improper resolution properties. Tried of course reinstalling Parallels tools which helps for a while. I suspect some bugs of course with Mountain Lion being new. Seems its always the case with Parallels and a new OS version. Anybody that can shed some light on the Silverlight issues would be great.
