EDIT: As of Revit 2011 the issue below is no longer a problem thanks to the new Properties Palette. Thanks Factory!
Prior to 2010, when you selected one or multiple views in the Project Browser, you were able to click the Properties button to bring up the View Properties dialog. However in 2010, there is no Properties button on the Options bar and no context menu is activated when views are selected. The View Properties button in your QAC stays grayed out nonetheless, so was this an oversight? I tend to think it was.
However, don’t freak out. The View Properties are still accessible via the right-click context menu.
