Umm, new questions. I can't seem to find the information on doing two things:

1) Display a mouse over text (how do I use Strings/Text object for a button?) on a button mouse over. Also, is there a way to show a tooltip (like normal windows tips, except in-game and over a button).

2) Change the cursor to another image on mouse over.

Maybe I'll find a solution as I continue going through the workshop.
