I have a toolbar with a few buttons on it. The image of those buttons is about 35 by 35. But, the class designer is resizing each button to make it bigger. The size is now about 55 by 55. From the property sheet, if I try to lower the value to 50, it does not work. The value always come back to 55.

This is taken too much space. How can I make my button only take the minimum space?
