Hi,

It should work by deactivating concurrent DNS resolution in Edit -> Preferences -> Name resolution. If you have this enabled it only uses DNS, but if it is not it will use also the hosts file. The problem here is that if you have improperly configured DNS resolution -e.g. you have configured a DNS which doesn't answer, or which tries to solve reverse mappings improperly- you will experience the DNS timeouts in the form of slow response in ethereal.
