------- Additional Comments From mikolaj.zalewski@gmail.com 2006-12-10 12:37 ------- This app is setting and clearing the TBSTYLE_FLAT style. Flat toolbars have a top margin of 0px while non-flat have the margin of 2px. Probably by playing with the TBSTYLE_FLAT the app is able to create a non-flat toolbar with a 0px margin. We reset the top margin after each TB_ADDBUTTON thus it doesn't work. When I will have some time I'll try to make this compatible with Windows.
