Hello,
I was unable to get past one of the stages of the Building A Slideshow Lesson as the page became unresponsive.
At the Instruction: Double Click on the Page to Open the Property Editor; A double click on this page produced no result. (Did not advance to the next stage of the lesson.)
Running Chrome on MacBook. Tried running this in Safari and same issue.
Screenshot here of state in lesson where issue came up.
Thanks
^MM
