Bug ID: 41700
           Summary: "Install Now" and "Customize installation" buttons are
                    invisible in Python 3.5 installer
           Product: Wine
           Version: 1.9.23
          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

The "Install Now" and "Customize installation" buttons do not appear on either
the regular Python 3.5 installer or the Python 3.5 web installer, not even if
you hover the mouse over the buttons or press the tab key repeatedly. However,
the installation continues if you click where the button should be, and the tab
key appears to move focus onto and off of the buttons even though there is no
visual feedback.

Note that you must set the Windows version to Windows Vista or later in winecfg
or the installer will only show you an error message.
