Research direction
Start by extracting and building VerifyCombobox.zip, then reproduce the ComboBox behavior in .NET 11 with DropDownStyle set to DropDownList. Trace the WinForms ComboBox handling for DropDownStyle and BackColor to identify why the displayed color is incorrect; done means the reproduced control shows the expected BackColor in NET11 mode.
