Hey guys and gals, I was wondering if anyone else has a problem like this. It doesn't happen to me very often, but man when it does it drives me bonkers. When I try to dimension a distance, it kicks out the dimension at a crazy angle as you can see. What I've scribbled in red is how I want to dimension it, but as much as I move the mouse, it goes to the places I have placed in the picture. How do you either avoid this, or make it go the way you want?

Thanks everyone.
