In some rare cases the PL advancement button disappears. This happens in just a few of our learning screens, and only seems to affect mac book pro users!
To solve this problem:
- Go to the module and screen you are stuck on
- Watch the video until almost the end of the time line
- Click where the arrow should be! (the mouse will turn into a hand when you hover over that area, even though the arrow is invisible!)
Here are screen shots that show where the arrow should be.
