I just noticed several WPF applications (Blend, VS.2010 in particular) are not rendering everything properly post 10.6.4 install. I did not have these issues before installing, but now icons and menus render strangely - mouse over will re-render properly sometimes. Parallels 5.0, MacPro4,1; ATI Radeon HD 4870 Guest is Win7, 8G, 4 processors devoted to it. Is there an update pending soon - it seems like it's been forever since a desktop release has come out.
