mozilla times out retreiving list of groups

[Seref Arikan]

hi, i have the latest rpm relase for redhat, and mozilla just can't get the
list of available groups from my usenet server. i am using outlook express
under vmware now, and oe, does not have any problem getting the list, so
it's not a connection issue .i don't want to use vmware everytime to use
usenet, so how can i change the timeout settings for this ? the same problem
exists for knode also, i just can't DL the list of available groups..
Regards...
