Trey,

I imagine it's because OldHeight and OldWidth are not properly initialized.

>Any idea why when I changed the beginning width of my grid and treeview in the designer the two controls would stop resizing when the below code is called in the form's resize event? It was all resizing fine until I changed the width value in designer on the grid (wanted to startout with a smaller size when the form is instantiated). Does changing the width of a grid change some other property I'm not aware of?
