@pkeading ,
yes dwg import works, no crashes so far.
But as Pat Stanford says, it's probably not a good idea to use VW2008 on Snow Leopard if it is your only setup, but in the past i had never really experienced any problems as Macosx updated and there was a warning from Vectorworks that it wasn"t compatible, they have a resposibility to their customers to always stay on the save side.
