Pecha

It works well for me all time, but today I have experienced the same problem. I've executed the following commands in the VS 2008 Command Prompt and this helped me:

<div>

1. devenv /setup
2. devenv /resetuserdata
3. devenv /resetsettings CSharp

</div>

Thank you for listing your tips.  I will give these a shot.  Hopefully this will do the trick.
