Unable to close installer from Quit button

[Sigmund Vestergaard]

On the first page of the installer the language to use during the installation is chosen. If switching between multiple languages, in the end you'll be unable to quit it using the Quit button. Normally when you press Quit a dialog appears asking you to confirm that you want to quit, but after choosing different languages one after another this dialog appears to be set to zero width. See the attached screenshot for an illustration. You can barely see the "dialog" in the middle of the screen.

Below you'll find Information about the release and the version of the installer:
