Windows 7 Snap and Dual Screen

Today I was trying to get 2 programs side by side as shown on the windows 7 advert on TV.

It didn't work, I could only get one program to snap to the outter edge but not the middle ..

There seems to be a bug if you are using dual screen, I guess because it assumes you want to move to a different screen when you drag to the side

A fix to snap windows side by side on dual screen

Click window you want to move to side - hold down the windows key and press either the left or right arrow button.
