title: Visual Studio C# IntelliSense not automatically displaying
body: <p>Just recently, my Visual Studio 2010 stopped displaying IntelliSense suggestions automatically while I am typing.  I can still press ctrl+space to get it to work, but it doesn't automatically show a list of suggestions like it used to.  I have already tried disabling all my extensions, restarting VS and the computer, and I have checked all the appropriate settings (Options -> Text Editor -> C# -> IntelliSense) to make sure that it is set to offer suggestions after a character is typed.</p>
  
  <p>Has anyone seen this behavior before?  Does anyone have any other suggestions for how I can get IntelliSense to go back to the way things were before?  If not, I might just have to do a fresh reinstall of VS...</p>
