I can't find a way to stop continuous dimensioning in Rhino 7

I can only describe it as continuous dimensioning. After making one dimension the next click, where I want to start another dimension, creates another dimension. I have been deleting the unwanted dimensions ( a bit of a pain), but after making an aligned dimension all subsequent dimensions are aligned on the same angle. I can’t find a way to stop this behavior. I never had this problem in R6.

Hello - set Continue=No on the command line when making dimensions.


OK, feeling rather stupid here.
