Widgets posted on Moodle sites hosted on Unix servers play on full screen, but trying to go back to regular size freezes the screen.

The only option seems to add a full screen button from the library, use this instead of a right-click to get to full screen, and ignore the message telling to press ESC key to go back to original size.

Full screen posts a huge message on the screen telling the viewers to press ESC to get back to regular size. It's too bad this must be ignored.

And, as widgets (or videos in video viewers) look better without a white button on the image, it's too bad the right-click option to get full screen and original size does not work.
