data grid - changing the header hilite gradient

[Shao Sean]

why does the data grid insist on replacing the nice gradient colours i  
have chosen for the hilite colour? the colour pane for the data grid  
only allows us to replace the dark gradient with a single colour, so i  
work through all the issues of setting the gradient of all the header  
hilites and then it goes and replaces it on me.. not a happy panda :-(

note: the background gradient for the header does not revert back to  
the default, just the graphic used for the hiliting..
