Lesson Videos too large - off screen

So I tried a first lesson on here, but not all 64 squares are on screen.

I don't see anyway to scale the lesson video.

Is there a way?

Is the zoom setting of your browser greater than 100%?

Negative.

Hit Command 0 just to be sure.

Have you tried a different browser?
Which lesson?

I'm using Chrome (because that's where the password is saved)

and on a Mac. I checked 5 or 6 different lessons and the video (and chess board) has to be scrolled up and down to see top and bottom. The 5 or 6 were all the same.

The 'old' lessons appear okay.

Here is a screen shot:

It maybe the aspect ratio of your screen. You should be able to shrink the board with the resize button.

Awesome, that worked. Thanks.
