I'm experiencing a glitch under Windows XP, using Visual Studio 2005. When working on code, for example implementing an interface in a class, the refactoring menu does not render. I have tried both the keyboard shortcut (alt-shift-F10) and clicking on the popup icon, both have the same result; the menu appears to render briefly, then flashes away and I'm left with the just refactoring icon. This is negatively affecting my development time, as a lot of the automation features in Visual Studio are available only through that context menu (as in this case, the "Implement interface xyz" feature). Has anyone else experienced this problem, or found a solution?
