I start with a blank canvas. I pull the default cube up to a level above ‘0’, and add a plane. I set the logic for the cube to rotate 1-degree on the Z axis when I press “S”. It works as expected. I then change the Physics for the cube to “Dynamic”, and try rotating it again with “S”. This time it rotates erratically and flies off the screen.
I found an issue relating to this on GraphicAll. (http://graphicall.org/62) I tried the download you see there, but I had the same issues.
Help?!
