Sliders on Mac, OK, on XP...beuh?

[François Cuneo]

Hello Everybody!
I'm using sliders on my applications. I'm working on Mac OSX.
When I create standalone for MacOSX or PPC, all is OK, but on Windows 
(XP), I see the slider, but only the "line", not the button.
Is it a property that can do that?
Thank you for your answer!
Friendly
François
