I agree with phoenix the layout is fine, but when the page is expanded in anyway the buttons and descriptions get mixed up.
But the issue of the Hints not showing could be because the "closeness" of the radar buttons and the length of the description. TW seems to not display hints that will overlap buttons. (don't know if this is a bug or what)
What you might want to do (to a copy) of your tours is move the radar buttons out further and see if this fixes the issue.
BTW I like the concept of what you are trying to accomplish, but the "small" tour window doses seem to distort the pano somewhat

To err is human ... to not try is just plain lazy
