the tutorial tells you to use the arrow keys. you can also use left/right click to advance them. It's just for the tutorial tooltip that you need to do this for.
Hi, this has been fixed. Are you on v0.66.7? (Check the version in the info panel via the menu). If you still encounter the problem after refreshing the page and the version in the info panel shows a lesser version, it might mean you have to wait awhile for the update to go live.
