You won't believe this.. when I try to start Blizzards Warcraft III and Max is running, warcraft gives a CD-ROM drive error.
"Please verify that your Frozen Throne disc is in your CD-ROM drive, then click on 'Retry'."
When I turn Max off, warcraft starts as usual. This is reproducable.
Windows XP, Max 4.5.7., Warcraft III Frozen Throne 1.20d
