Polygon Editing

So I've just upgraded to 10.1.  Now that I have installed 10.1 I'm having trouble with the very simple task of creating a polygon. 
When I'm adding multiple vertices in order to create a curve or something, it's like some of the vertices are ignored.  Very strange. When I go back to adjust or add vertices the whole polygon shifts shape and again some of the vertices don't show up and it automatically takes some odd shape.  I've searched around in edit options but nothing seems to be causing the issue. 

So what now? Reinstall?
