@lisa563 Hm - I have heard of such issues but never been able to reproduce them. Would you be able to locate the Chrome Developer Tools and check if you see any kind of error there, e.g. in the "Console" part?
To open the developer console in Google Chrome, open the Chrome Menu in the upper-right-hand corner of the browser window and select More Tools > Developer Tools. You can also use the shortcut Option + ⌘ + J (on macOS), or Shift + CTRL + J (on Windows/Linux).
