After upgrading the notes dow not fill out the entire Notebook area. They only show up halfsize with white space on the right. If I expand the size of the window the whitespace (or should I say gray-space just gets bigger but the content of the notebook remains narrow. If I open the notebook in it's own window then it's the normal size.
Attached is a screenshot showing the issue.
I looked through Preferences and don't see a new setting that might have caused this behavior. It's really a poor use of screen real-estate. There is no handle to grab that screen on the right and resize it to fill out the right hand side.
Thanks.
