I have to report also my impressions:
1.04 goes fairly smooth and fast than 1.02, but the infamous chat CTD is still there.
I've tried alternatively both with the TAB key and SHIFT-F12.
Everything seems to go ok, until a sudden, fast CTD when pressing either the TAB or the F12 keys.
Nevertheless, these have been rare CTD, far less frequent than with 1.02
The strange thing about it is the sudden, totally unexpected nature of these chat CTDs
In 1.02, for example, if I was hosting, I was starting to get a pair of latency messages from a player, then he banished...He got a chat CTD
Now, in 1.04, there are no previous latency messages: a player just disappears, then he reports to have had a sudden chat CTD
I've had myself 2 of these CCTD: one while hosting, and another as client
Everyone was using DSL connections and NA 1.04 version
