toolbar, flat style

Hello,

im trying to create a toolbar with flat style under windows (xp). When i
enable XP styles then the toolbar shows flat. When i disable the xp styles
then i see only 3D Buttons. But the style is set to wxTB_FLAT

my code:

wx.ToolBar toolbar =
this.CreateToolBar(wxNO_BORDER|wx.ToolBar.wxTB_HORIZONTAL|wx.ToolBar.wxTB_FLAT);

toolbar.AddTool((int)Cmd.ToolbatButton1,"test", Images16.Mondrian);
toolbar.Realize();

is there something wrong in my code?

Alex
