Help doesn't work?

When I’m in the parameters panel of an operator (upper right corner) and click on the ‘?’ for help, nothing happens. Is there some preference I need to set? Or…???

No preference, this should work. So, questions:

Is this true for all operators?
What version of TouchDesigner are you in?
What is your OS?
Is there any message in the textport (alt-t) when you try to get help?
What browser are you using? Help should show up there…

Restarting TD wasn’t enough, rebooting the machine fixed the problem. But your list of info to supply for future issues is noted! Thanks!

That is very odd. If you ever figure out how to get back in that state, please report again in this post!
