Hi Kevin.

Very nice looking!

>From what I can see, the UIEnable is being called for EVERY icon on the bar each time the mouse moves over any part of the UI.

Do you have code in MouseEnter, MouseMove, or MouseLeave for the page frames that changes the selected page? If so, when that happens, UIEnable fires for all of the objects on the former page and all of the objects on the new page.
