So, I've worked around this, but I'm interested to know if there's any insight onto this issue I've run into.
It seems I cannot have a RadRibbonBar and an asp:requiredfieldValidator on the same page. Doing so causes a new replica of the window to open when you use any buttons on the RadRibbonBar. For example, using a button that simple closes the page does what it should (closes) but causes a new window to open with the page that was just closed.
