>The exact problem I described. Don't forget, I'm using .NET CE. I coded the class yesterday (took me some time to research, since I already forgot some C# I knew by ~ 6 months of not using it), then I re-coded my form using three new instances on the new grid class and then to my dismay found this problem - that seemed to be unsolvable.

I just tested in CE as well. No problems.
