Vista工具栏如何忽略或找出边框填充设置？

I have a toolbar developed under older versions of Windows that is largely cut off under Vista due to the window new border padding. With the default border padding of 4, the everything on the toolbar is shoved four pixels down and to the right, and then everything is cropped four pixels from the bottom and right sides. I don't really care about the horizontal dimension as much, but vertically this means the application loses eight pixels of visible content.I have a toolbar developed under older versions
