Mutate tool not working education mode

[Sgell]

I tried playing fold.it with my class on the new web-based version. Almost every student got stuck at the protein design stage because they couldn't keep the amino acids highlighted to press the mutate button. While some students were able to make the mutate function work, there wasn't a clear pattern for those who were successful vs. those who were stuck. I tried Chrome vs. Safari with no success. Most studens use Macs.

Thank you for this feedback, Sgell.

I see this issue as well on the "Intro to Design" level (clicking the button M does nothing in Chrome on my PC and my Mac).
However, as a workaround for now, pressing the keyboard shortcut "M" does work (when a valid sidechain is highlighted).

I will report this bug, but please let us know if using the keyboard shortcut doesn't work for you!
