Thank you for your code. Your example gave me some ideas on a totally different project which is a bonus.

Unfortunately, I'm not talking about scrolling a grid by rotating the mouse wheel - I'm talking about scrolling a grid by clicking on the mouse wheel button and then moving the mouse up or down to begin auto-scrolling.

UPDATE: Just read my original post title and realize its confusing and not accurate. I apologize about that.

Thanks again for your help,

Malcolm
