Can't Move Textbox in UML Diagram

[robertf]

I'm creating a UML Activity Diagram with Visio 2007. I have three swimlanes,
a couple of action states, some decision symbols, and some control flow
arrows. I'm trying to create guards (e.g. [a_guard]) near the decision
symbols using Textboxes. However, when I create a textbox, I can't seem to
drag it where I want it. Each time I drag and release the textbox, it snaps
back to its former position. If I try to move it with the arrow keys, it
does the same thing like a typewriter carriage.

Does anyone know how to move a textbox?

Thanks.

I think you should be using a Constraint shape for this, not a text box. The Constraint
shape has a handle (yellow diamond) that you can use to connect the constraint to the
shape with the guard condition.
