I have a window with its own H and V scrolling. I'm handling the event like this:

case WM_VSCROLL:

        SetScrollPos(hWnd, SB_VERT, (int)HIWORD(wParam), TRUE);

        break;

all I want is for the position of the scroll bar to stay once I release my mouse but what it's doing is just going back to the top after. What am I doing wrong?

Thanks
