My windows don't snap anymore!

Hi! I've got a Macbook Pro running Mountain Lion. I used to be able to snap windows to half screen or full screen by dragging the window to the menu bar or the sides however I have suddenly been unable to do so! Please help!


sorry wrong forum***

First, please do not cross post. If you think you posted to the wrong forum, ask a Staff member to move it for you rather than duplicate the post. I removed your other post.

In Mountain Lion you should see diagonal arrows in the upper right corner of the application you're currently working with. You can click on those to go full screen. (Not every application supports this, however.) You should also be able to grab the application sides or top bottom and drag it to the size you wish.

As far as I know, OS X doesn't do this natively. You need a third party app like BetterSnapTool or Cinch. Did you have such a tool installed before?

Yikes! I just realized it was HyperDock that was allowing me to do this, but I've had the app so long that I thought it was a native ability to snap the windows (like Windows 7 does). I'm a bit embarrassed but thank you for the help chscag and Oneironaut!!

Yeah, so all you need to do is download an updated copy of HyperDock.
