Popup in help browser

Hello,

starting today, Matlab some popup overlay has appeared in the built-in help browser pop-up (after pressing F1).

I don't see any 'x' or other method to make it go away. It may be hidden outside of the window? Reloading the help browser makes it re-appear after a second or two.

Any way to get rid of this?

Thanks,

Sometimes, simply closing MATLAB and restarting it can clear stuck popups.

This looks like the same problem recently reported in https://www.mathworks.com/matlabcentral/discussions/general/880710-how-to-get-rid-of-this-opc-ua-server-survey-pop-up

Can you contact Technical Support for this? Please add the link to this thread to the question and mention to the case owner I like to be involved.

If you click and drag the dotted array in the lower right corner, can you drag it big enough to see the titlebar X or a button at the bottom of the dark survey window?
