Hi Ben--
I was just having a look at https://caffeine.js.org and I presume to run code I click the circular arrow (fifth icon down outside left margin) but every time I get a Halt.
Hm, no, that button is a placeholder for "rotate window". :) I guess I should take out the buttons that don't work yet (so far only the top two "close" and "move" buttons do).
To run code, you should be able to just interact with the Squeak UI normally inside the window.
thanks,
-C
