Brent, Thanks for posting.
Do you have the notes tool Auto-hidden at the (top, bottom, left or right)?
Does it matter at which location the notes tool has been auto-hidden at when you run into this issue?
Does it matter if the other tools are auto-hidden at the same location when this occurs?
I have auto-hidden the notes tool at all locations noted above and have been able to re-size without any problem. If you can provide further information that would be great.
