Manipulator turned into a yellow ball [SOLVED}]

Sylvan

Whenever I select an edge and extrude, my manipulator turns into a yellow ball. I thought it was the manipulator being in rotate mode. But no matter what mode I select, it just stays like a yellow ball. I am pretty sure I pressed something, but what on earth could it be?

Oooh, it turned out that I had two faces layered on top of eachother and the extrusion tool couldn't do anything with that. Deleted one of the faces and problem was solved.
