On a Microsoft Windows XP Service Pack 2 (SP2)-based computer that is configured to use themes, the horizontal scroll bar that is used in forms may appear to be inactive. For example, the scroll bar does not respond to mouse controls or actions. This problem may occur when the scroll bar is part of a form that is, in turn, part of another form.
Note This problem typically occurs when you use forms that are designed in Microsoft.NET programs that use the System.Windows.Forms.Panel module. You may also experience this problem with forms that are created in Borland Delphi programs that use the TScrollBox component. This component is part of the Delphi programming language that is used to create scroll bars in Delphi programs.
This problem may occur if the code in the Uxtheme.dll file incorrectly calculates the horizontal scroll bar position in the form.
