Please don't mark as a duplicate (this is a similar question). I am making a Database diagram in Visio 2010, but when I add a table entity, I can't resize it. I've tried changing the protection, I've messed about with the ShapeSheet, and the best I can do is to get the points around the edge to turn blue (they still don't drag though).
The weird thing is, when I add a different entity, and set the protection to None, I can reshape it just fine! Why is this? Am I missing something or is Visio just being weird?
