I can't seem to find a way to unlock UML shapes in Visio 2010. In a composition, for example, I used to be able to move the multiplicity text boxes around (Visio 2007 and earlier versions), although I had to go through contextual menus (something like Format > Protection...).
I am having the same issue in Visio 2010: inability to move the multiplicity boxes. I tried the suggested solution, both on the shape and on the text box, but I still cannot move the text. Is there something else I'm missing?
It used to be, in 2003, that I didn't have to do anything special other than use the text box tool, so this is pretty frustrating.
