Add pages pop-up freezes

Hello, after working about a week with Wix Code, my add pages pop up freezes every time I want to add a new page: doesn’t matter what kind. Can’t buid any further.

Just added a screenshot to make clear what happens.
Anyone who knows what happens or where to find a solution?
Tried allready to logout and login again.

It seems that your screen resolution is too low. The same thing happened to me a while ago when the browser window was too small. Make sure your browser window is fully maximized, and if that doesn’t help, try to increase your screen resolution.

Screenresolution is 2160 x 1440.
Fullscreen browserwindow does not solve problem but…
But changing browser from Firefox to Edge solved problem!
