I'll see what I can do. If you could walk me through step by step what exactly happened and went wrong (such as what you mean by mouse not controlling view angles: was the camera stuck? Could you see the mouse on top of the screen just moving around? Something else?) there's a greater chance that I'll be able to help you.
I'll be honest with you, though. I haven't seen this bug before which makes it tricky. And, it's over a year since I've touched the code in this game, so I'm not at my sharpest for figuring out what's wrong.
