When you press "Save As..." and try using the arrow keys, the saving window immediately closes, not letting you save. I usually use the arrow keys to navigate on the naming field; Up to move the beginning of the name, or Down to move to the end, or Left and Right to move into a position between the name where I would like to write or delete something. I also use arrows to navigate the specific finder location/folder where I want to save. Now, the only way I can do anything on the "Save As..." window is to use the mouse. Please fix this.
