(SOLVED) Visual Studio 2010 user interface is unresponsive
The Visual Studio 2010 user interface has a tendency to become unresponsive at times. I discovered VS2010 has a configuration option that you can adjust to help with this problem.

You can uncheck the ‘Automatically adjust visual experience based on client performance’ checkbox @ Tools > options > Environment > General. This seems to have made a difference and VS2010 doesn’t lock-up as much.
