All of the XNA examples I have seen don't show a mouse pointer when the mouse is being moved around. I realize that I could just have an image drawn at the mouse position every frame, but is there an easy option or some easy line of code that I could use to enable the default mouse pointer until I decide to make my own pointer image

Here is a link to a beta 2 article I wrote that shows you how to make a custom mouse pointer, you might want to have a look at that.
