I created a Home button of 20 pixels high by 70 pixels wide on a 1200 pixel wide Master page.
When I attempt to make a similar button on another page, it is larger than the Master page button and I cannot force the numbers to 20 and 70, Muse insists on making it 21 by 73 pixels.
I can go back to the Master page and change the size to 21 & 73 and the two buttons now match in size on the other page.
If I copy the Master page button and paste it on the other page, it expands to 21 x 74 pixels which can be reset to 20 x 70 pixels. But the button I created on that page will not resize below 21 x 73 pixels although I can make it larger.
Am I doing something wrong?
Please, give us a .muse file with only these buttons, to demonstrate the problem. To do so, you may use Dropbox or a similar file sharing service.
