Odd behavior after udate to Beta 20

When I click ‘Draft’ at the top of my document there is now a hesitation and a bar showing the percentage which I never noticed before. On the screen where you edit/type in text, the section goes to a small square as well. It then goes back to normal after finally bringing up the section that I want.

The document isn’t very big itself, close to 90k with no pics.

I’ve tried doing an indexing of the document but there is no change.
