I have really annoing problem with my Unity 3.5.3. I installed unity 3.5.3 and my Q,W,E,R keys didn't work as expected, so i opened preferences->keys to figure out whats wrong. All settings was fine(Move tool mapped to "W" key and ect.), but when i selected "Move tool key" in preferences, and tried to put "W" for myself, I saw that key changed from default "W" to 172(which probably "W" letter code or something), and after that, when I click "W" all works as expected. But I still can't use for example Vertex Snapping, because unity doesn't recognize "V" key, and I can't change it from preferences. May be someone knows what is the problem, and how to fix that.
