Grant,
The grid I subclassed from the foundation grid class exhibits the behavior you describe.
My abstract grid, on which I base all of my grid objects, does not.
I cannot tell why just yet. And I'm out of time here.
I'll pick it up again in the morning.
Meanwhile, one of the VWPs (Very Wise People) on this forum may jump in with the actual answer.
Good luck.
