Bug #: 29553
           Summary: Sonic R demo installer doesn't allow manually typing
                    an installation directory
           Product: Wine
           Version: 1.3.36
          Platform: x86-64
               URL: http://www2.sega.co.jp/download/pc/sonicr/sonicr.exe
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: user32

When the installer for the Sonic R demo asks which directory to install to,
typing the desired location manually doesn't work: the preselected directory
text is deleted, but no new text is accepted. It's still possible to choose a
different directory via the "reference" button.

This issue first appeared in 1.3.31:
