Grab the corner or the crop and drag it, the box will flip automatically. Then you can click the padlock next to the ratio setting to lock it in the aspect you want.
It's a bit different but you'll soon get the hang of it!:wink:
It can be a bit tricky to figure out... sometimes I'll actually cancel the crop tool, go to a different photo and then go back and start the crop over on the picture again. Seems once you figure it out thought I LOVE the crop tool though.
Grabbing a corner and pulling it down is just like using the Free Transform tool in PS when you are rotating an image -- very easy -- but I guess hitting the "X" key (which I did not know about) is much easier -- will have to start doing that now
