Where in Gmax would I find a listing for any or all the Mouse Rect and Visibilty that I have set ? I was hoping for some summary like the Animation Manager has, to keep track of where and what for Attach Points.

There is no such "summary," unfortunately.You need to select the object to which you've attached a visibility condition, then right-click and open the Properties window. You can see the String that was inserted in the "custom" tab.
