Ok, so this is the problem. Once in a while when I play any game it goes fine, until I am killed and then I cannot respawn no matter what. My mouse navigation works, but I just cannot respawn at all, no matter what buttons I press.
It helps to restart Nexuiz. However, sometimes I can play for a while but then suddenly I cannot respawn, this mostly happens after map change or when I first connect to a game. It has happened that once in a middle of a game that I couldn't respawn either.
My setup is Windows 7 RC (don't know what revision and don't know how to check either).
Nvidia GeForce GTX 275 with latest drivers. Core i7 920 2.67 GHz.
