TB 3.1.1 "What's New" Tab

Hi
Have just updated to 3.1.1.
This maybe a silly question, but how do I stop the "What's New" tab from opening every time I start it.
Is this happening to anyone else?
Thanks in advance

Just Updated to 3.1.2 same thing happening. If I don't shut the tab, the next time I open it 2 tabs open, and so on.
Will probably go back to 3.0.6 if no one has an answer.

Thanks
