I was in the middle of doing something tricky this morning and suddenly this Edge screen opened (full screen) with no close button, interrupting my thoughts. No close button and when I right clicked on the tool bar icon and clicked on close window, nothing happened. Eventually, I had to begin their tutorial and then a close window appeared and I closed it and could back to work.

I once tried to use a Windows simulator in some version of Unix, but the editor just did not work properly.
