According to the author Browser Support is:
Works with: IE 5, IE 5.5, IE 6, NN 7.1, Mozilla 1.3 Opera 7.01, Opera 7.22, Phoenix 0.5, Firebird 0.7 on Windows, Camino 0.7 on Mac
Fails in: NN4, Opera 6.05 on Windows. Safari 1.0, IE5.2 on Mac
Im happy enough with that compatibility as theres a full text sitemap for people for whom the menu doesnt display properly.
