Menu bar has lost functionality/is broken

[Eliot Brown]

I was coding for a website and as such alt-tabbing between the IDE and Chrome to test, when I alt+tabbed into a nautilus window. The window had lost its menu bar, and as such has lost minimise/maximise/close/settings functionality. I then opened additional programs, terminal and software centre; both of these have no menu bars on opening. Rather obvious problem there! Screenshot of the issue enclosed.

I will now restart to see if:
a) That provides a temporary fix
b) The bug can be reproduced and exactly how that was done etc.

Missing screenshot showing problem.

Thank you for taking the time to report this bug and helping to make Ubuntu better. There have been many changes in Ubuntu since that time you reported the bug and your problem may have been fixed with some of the updates. Could you check and see if the issue persists?

Thanks!

[Eliot Brown (eliotjbrown)]

Given I couldn't reproduce the bug at the time, or at a later update after additional installs and it hasn't been duplicated by anyone else, I'll put it down to sheer bad luck! Suitable to close.

Cannot be duplicated, hasn't affected anyone else.
