Back on 11.10, whenever I would take a screenshot, there would be a preview that gave me the option to either copy to a clipboard, save image wherever I wanted to, or cancel (in case I bumped the PrntScrn key by accident).
But, I'm on 12.04 and that option seems to be gone. Whenever I press PrntScrn, it does the typical sound and flash, but I don't get the preview. I originally thought that this option was removed from Ubuntu, but whenever I was helping my brother on his new 12.04 install, I found that the key gives the preview on his computer. He has a brand new 12.04 install, but I have a 12.04 install that was upgraded from 11.10.
Does anyone have any ideas what may be wrong?
