Alright, I realise what the problem is now! It isn’t that End Routine on press is never, it’s that Save mouse state is also final. This stops it sampling each frame as it doesn’t need to listen each frame to store the click or to end the routine, so it doesn’t. If you set Save mouse state to each frame or on click then it starts listening!
After this you then get a different error - that mouuse_2 isn’t listening, even though the code is there. This is because we overlooked stopping Maussprache, but this is easily remedied! Just copy and paste whatever condition you have for mouuse_2's Start into Maussprache's Stop, so that Maussprache stops listening and mouuse_2 can start.
Hope this helps!
