When I first installed Ubuntu 12.04 LTS 32.bit from a Live-CD without internet connection and any updates the snapping feature worked fine for windows of all applications. However, after some updates and installations it stopped working. I can no longer drag a window to the edge of the screen and have it resized. Thinking the problem is from my lack of experience I did a clean install of Ubuntu 12.04 again with internet connection; however, the problem still persists and I am fed up with this. Do you have any suggestions for remedy? Thanks in advance.
P.S: The feature when working properly was just like that in Windows 7. I am a new user BTW so I might be skipping some important details, and I would be glad if you can remind me of them.
