Summary: Pressing "Details..." button causes nothing in
                    Nullsoft Install System
           Product: Wine

          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED

When installer starts copying files, "Details..." button appears. Pressing this
button shows a read-only edit box that displays current progress on processing
files. It works on Windows, but not on Wine. I've tested it with VLC's and Qt's
installers.
