Shadows are being weird

Hello All,

I was using unity today and I have found that in my test scene the shadows are being weird in the corners here is a picture

Anyone know how to stop the shadows from coming away from the corners of the roomy things

It appears the image didn’t load so I uploaded it to my web server http://www.mcmorcraft.info/Shadows.PNG

Have you tried adjusting the Bias setting in the inspector for the shadow properties of the light that’s doing the casting?
