One other parameter that must not be set is pbAutoColumnSizing in the grid itself. Should be intuitive but could be overlooked.

Also, using the following in the grid object rather than setting the properties directly in the column object might be necessary to avoid the dreaded "Com object addressed before it's been created" error. Sorry, I don't remember the exact syntax of the error...

Code:
          Procedure Activating 
              Forward Send Activating
              Set ComAutoSize of owwccat_description1 to True
              Set pbResizable of owwccat_description1 to True
          End_Procedure
