CCS/TMS320C6713B: problem when CCS halts and can't find C source code

Part Number: TMS320C6713B

Tool/software: Code Composer Studio

Hi

When I pause the 6713 CCS is trying to locate C source code:

I can fix this by putting the source code in the project directory, but would rather it be in another folder - how can I set this in my project/properties?

thanks

Danny
