Please let us know more details about the problem. First of all, which slider you are talking about? The CExtSliderWnd window, the CExtBarSliderButton toolbar button object or the CExtGridCellSlider grid cell object?

The CExtSliderWnd class is based on the standard slider common control. We used a tricky technique based on WM_CTLCOLOR*** messages to repaint its background. Our slider generates a brush object which is based on a bitmap with a size equal to the slider’s client area. This bitmap is created as an image with a theme consistent background. This technique was used because there is no other way to repaint the background of the standard slider common control. Unfortunately the slider does not request a new background brush in all the cases when it needs it. The problem can be fixed by invoking the CExtSliderWnd::UpdateSliderWnd() method.
