Ok, but only if it's fresh. Once fish have been left to sit for a while, they aren't so goodly anymore.

If the viewport is a panel, or derived from a panel, then dragging and dropping to it should be no problem.

I was just looking at the 60Hz value. I hadn't thought about it that way. With GDI, all of my drawings are faster than that, individually. The issue is that if I have to do 200 of them, then they are slower than that. It really does look like the XNA route would be superior, eventually. What I wonder about is whether the performance of XNA is so tied to the hardware quality (especially graphics memory quantity) that I might have problems with older systems.

I guess I should also confirm that XNA is not a Vista/7 only, technology.
