starcraft with wine

[threadhead]

heyho.

i finally got starcraft running on my linux box and played
a few singleplayer games.
but when i try to join a LAN game (udp connection)
starcraft tries always to download the map even when
its already on my drive in the maps directory.
sc downloads and finally says that he can't
download the map.
maybe thats because of the fiesystem, because i dont
have windows installed on my box, its only a fake created
by wine.

any help would greatly appreciated
thanks threadhead
