There is a known problem with Visual Studio 2010: when you open a context menu in the Solution Explorer it doesn’t always get expanded to fill to available height of the screen and you get a vertical scrollbar. On top of that, sometimes the mouse scroll doesn’t work also, and you have to move the cursor to the up/down arrows to scroll it yourself, which only adds to the frustration. Usually I work with high resolutions (1920x1080) and the context-menu is shown without a scroll so I’m not that bothered...
