>If you have been able to get this to work, Ed, you are truly more resourceful than I (which I suspect is true anyway :-)). I once spent a full 3 hours trying to get 2 grids to completely synchronize, and while I got pretty close, I couldn't get it to work flawlessly. AfterRowColChange doesn't fire consistently enough to use as a Synchronizer, and neither does Scroll. I am interested to hear if you have ever implemented this successfully.

I have never been requested to do this :).
