>>> Hi all,
>>>
>>> I've written a custom view and done some optimisation of the drawing calls so only the exact areas that need redrawing are passed to the 'setNeedsDisplayInRect' function.
>>>
>>> All was working well, until I embedded my view into an NSScroller.
>>>
>>> Since then my custom view seems to be being invalidated by grid sections.
>>>
>>> I've included a link to some pics to try and better show.

>>>
>>> I added the green borders around the dirtyRect area to better show the problem.
>>>
>>> Thanks,
>>>
>>> Billy.
