Hi
I've just installed Office 2013 (64bit), and there is now a large lag (~2s) between right clicking, and the context menu appearing (only in Office applications)
After about a second the shadow appears, then followed by the menu itself.
This lag is also present to a lesser extent when scrolling.
I'm running Win 8.1 on a Mbpr using bootcamp, all other applications run buttery smooth.
Any ideas?
