drag to crop does not work

[Irwin]

prior to the last update of Camera Raw, there was no problem after chosing the crop tool dragging a selection and double clicking the selection to crop.

Now that no longer works. Instead clicking and dragging just moves the entire window.

Try resetting the Camera Raw preferences.

In Photoshop, go to the Photoshop menu > Preferences > Camera Raw.

Click Camera Raw with the Command key pressed.

Click Yes in the dialog that follows. (screenshot below from Windows)
