Thank you David!

I don't know if I want to change this permanently or not. What are the drawbacks? That is, why isn't it the default? Is it so people will be able to use non-cg commands in a cgwindow with longs used the wrong way?

(I just happened to see the long integer thing today when I was looking for something else. I even hacked up a version of cgcolor over the weekend, that accepted RGB colors given as hexadecimal strings. Worked fine, but felt a bit stupid when I found out about the longs... :o)
