hi, okay i wanted to try the new animation system (mecanim) and i made some animations and all that stuff. then i made a animator controller and worked a bit there and it was going fine. BUT then i wanted to make the transitions i made the transitions from idle to walk, and walk to run. then when i pressed on the transition arrow the program crashed. i've tried to do it many times and crashes every time. Anyone know what could be wrong? PS: using unity3d free version.
