Hi vanncad,
Were you trying to make the band taller or smaller?
The smarts behind it were designed to make it get bigger to handle multiple lines of text, and to snap to a grid setting, which is stored in the very top rectangle.
You can make the shape taller by selecting it and adding some carriage line returns.
You can make it smaller by selecting it and choosing a small font size, AND changing the grid-size setting in the top rectangle. To do that, select the top rectangle, then Window > Show ShapeSheet.
There's a user cell there:
User.GridRounding = 0.25 in*Sheet.1!User.AntiScale
Just change the 0.25 to something smaller.
Sounds a bit complicated, but if you do this, then you won't break anything that was intended by the solution developer.
