2 rows of menu items

I have 2 rows of menu items in my Unity. I had reset the layout and reinstall it but the problem still the same.

Does anyone has any idea on how to solve the problem.

Thanks a lot.

Check around, apparently there are hundreds of reports (just in this forum here) of people getting double windows opening the latest Unity. I don’t have the problem so I never read the answer, but it’s all out there in the subject lines on this forum.
