Weird icon won't let me sketch anything!

I'm trying to start a sketch of a new part, and when I select a plane, the mouse pointer turns to this weird thing that won't let me select Line, Rectangle, Circle, or anything from the drawing toolbar to start a sketch.

I'm trying to do a print screen to show the pointer I'm talking about, but the pointer does not show up in the captured images.

But, picture a regular mouepointer with a plain green square to the right and a yellow square rotated 45deg with a green centerline through it below the green square.
