It will break out the "NullPointerException Error" in org.xith3d.test.input.PointAndClickTest.java.
We can change the local variable - "canvas" in line 287 to global one. There will be no more error.
I have no authority to commit the right file. So, I post it here to inform you to fix the bug.
In addition, how can I get the authority to develop this project together with you guys.

Hi Andrew,

thanks for the report. I have fixed that bug. It was my fault.

You need to send me your sourceforge nick name, so that I can grant you dev access.

It's fine. I've sent my sf's username to you.
We are recently researching on the dynamic simulation for robots. We've encountered some problems, which are: the efficiency is a little low(while running a very simple application with dynamics, the CPU usage is about 50%), the robot control is hard to achieve.
So, does anybody here have some same experience? Or does anybody have some simple application for robot simulation with the physics engine?
