[ros-diffs] [jimtabor] 43101: - Working with Michael Martin to fix the LoadMenu callback bug. MenuName is a variable string buffer and not a pointer. The minimum size is always four bytes. Initialization of the structure, zero out the memory, allowing Intersource check to function as it should. To make it Intersource, use the first word character in the buffer.

- Working with Michael Martin to fix the LoadMenu callback bug. MenuName is a variable
string buffer and not a pointer. The minimum size is always four bytes. Initialization of
the structure, zero out the memory, allowing Intersource check to function as it should.
To make it Intersource, use the first word character in the buffer.
