Inset in Blender not coming out even I seem to have screwed up something that allows you to inset evenly, I think I have tried every combination of settings in inset and pivot center and even is far from even.  I tried uninstalling and re installing blender 2.71 and get the same result.  The image attached is a simple default cube that I tried to inset evenly.  I have also attached the blend file link  help??



Blend file here.
Your insets are distorted based on object scale. To fix this, you will need to apply your object's scale(Ctrl-A>Scale).
