Chat not working in game, Enter Key doesn't respond

[wc4482]

Lol no, believe me I checked that a few times.

It's very strange. 80% of the time I simply cannot use chat or /commands at all, but sometimes it works all of a sudden. I don't know how else to explain it. I'm at a loss.

It is probably a windows vista problem?

My friend is also having this problem. He is running Vista also. He told me most of the time he can't use chat or any /commands.
