For some inexplicable reason, I recently an unable to use the Expressions (Watch) window. Whenever I first launch the debugger, I get a "Problem Occurred" dialog box that says: "'Asynchronous viewer input update' has encountered a problem." with an internal error of "Argument cannot be null". I am running CCS version 5.1.0.09000.
Any clues here would be greatly appreciated, as this has made my last few debug sessions rather painful.
The event in the error log is as follows:
