Trying to save my word cloud and it does not save to myy Macbook

The first time I created the word cloud I saved it as a .pgn file it worked fine. The second time I modified the word cloud, saved it, visualized it and then tried to save it to my MacBook - nothing happened. I duplicated it and tried it that way - still not being saved.

You are clicking on "Save as PNG" button in "Grab and Share" section, right?

Please try changing its name to somethink like "Cloud5" and save.
