Bug ID: 43838
           Summary: this ComboBox highlight effect happens on all Windows
                    versions but not on Wine
           Product: Wine
           Version: unspecified
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]

When run on Windows, this simple application (one form with EditBox and
ComboBox) automatically highlights the ComboBox on startup.

When run on Wine, it doesn't.

This only happens when:

- The ComboBox has a pre-selected item which is on its list of available items.

- The form OnResize event updates the font color of the ComboBox to clBlack
after all the form components are already drawn.

I'll include a testcase with source code.
