When resizing a control it snaps to the wrong guideline

[flatliner60]

I have multiple guidelines on a Windows XP User Interface Diagram. I resize
(to the right) a control that is snapped to a guideline on the left, when I
get to another guideline as I resize, it instantly snaps to the guideline on
the right and scales at 10x speed backwards (to the left).

I'm not sure how well these shapes work with guidelines. In general a shape
cannot glue to more than one guideline at a time.

Internally when working with these shapes, we use the Align Shapes feature
quite a bit.
