Thank you Oginme.
You are correct, I did not go to the Profiles Library. Instead I selected the profile during recipe design.
It opened up a window with the defined profiles and a Create Mash Profile action.
What I was suggesting is another option on that sheet with the Edit action which in turn could open up a dialog box indicating that the way to edit a profile is to use the Profile Library.
Again thanks for the pointer.
Which leads to the next question, if I update an existing profile, does that update ripple through all recipes or is the newer information only in the recipes that selected that profile during the design process?
