Button size getting change on font size change

[SachAccess]

Hi,
I have few buttons on a form.
Am trying to change font size on these buttons.
As soon I try to change the font, button size is also getting changed.
I do not want to change button size. How do I lock button size.
Tried searching options in the properties however was not able to find.
Can anyone please help me in this. Thanks.

How are you changing the font?
Are you using Themes?

I can not replicate the behavior of your button.
Can you post a db that would illustrate the problem?
