[Pharo-project] windows 64 bit: printing NetNameResolver localHostAddress fails even after evaluating NetNameResolver initializeNetwork

[Ramiro Diaz Trepat]

I am having the same issues trying to connet a Magma Client and a Magma
Server in "localhost" using the latest Pharo on Snow Leopard (Mac).
It is this issue with NetNameResolver, I couldn't find a work around yet.
 Forcing '127.0.0.1' for localhost used to work before, but not anymore.
Same image and code seemed to run fine under Linux though.
Cheers
