With the newest releases I can't get a recipe selector interface opened when I try to create a new chain. In older versions you were able to add a new chain and then right click on the empty chain icon to open initial recipe interface. Was there a change or is it a bug?

hello
what is your version?
have you try the hotkey?
some time the panel is out of screen try this command
/helmod ResetUserUI

I am using the latest version. I investigated a little bit and thats what i found:
- in vanilla helmod works fine
- full pyanodons suite only shortcut works
- Latest Space exploration 0.3 helmod doesnt work at all

It's strange
another player play PY and often use and he have no problem, I check PY and I have no problem
I have tried Space Exploration 3 and that mean work fine
could you check the factorio log file?

Thank you for your help! I followed the steps provided and recipes show up. I still have to use a shortcut key but thats fine.
