I was re-organizing my GUI, copying and pasting labels and textboxes into a tabstrip control, when all of a sudden, my textboxes grow larger...

Now they all have a height of 360, not 285, like default. And I Can't Shrink them below 360! Resizing with the mouse or typing the property directly will not let it go below 360. What can I do, besides re-drawing millions of textboxes?
