Problem with sliders in Unity 3

Hi,

I recently ran into a problem with customizing sliders in Unity 3. When I want to set a different thumb image in a GUIStyle, the thumb image won't show up, even if the slider's thumb position gets updated if I click on it. I used to do this without problem in Unity 2.6. I submitted a bug but I wanted to know if anyone else had this problem and/or if you know a workaround.

I simply changed the normal and active images in the thumb style as well as the normal image in the slider style.

Code (csharp):

1.  
2. var mySliderStyle : GUIStyle;
3. var myThumbStyle : GUIStyle;
4.  
5. private var playSliderPos : float;
6.  
7. function OnGUI () {
8.     playSliderPos = GUILayout.HorizontalSlider (playSliderPos, 0.0, 1.0, mySliderStyle, myThumbStyle, GUILayout.Width(100) );
9. }
10.
