I only see this painting issue in with a Delphi 2009 compiled installer. The Delphi 2007 installer (and earlier Delphi versions) do not have this issue. Doesn't that mean that it is a Delphi 2009 bug from which the JVCL Installer suffers?

The TCheckListBox does not work with DoubleBuffered=True. And because of the new Delphi 2009 property "ParentDoubleBuffered default True" the DoubleBuffered property of the TCheckListBox becomes True if the installer is compiled with Delphi 2009.

I've added code that turns ParentDoubleBuffered off for the CheckListBox.
