plugin not working

Hi there,
I’ve download the plugin but it doesn’t seem to work out for me.
When i press the crop option there’s a window opening where i can choose the part i want’ but then i don’t have the button to get out and save it, so the picture docent really crop..
I’ve tried to press the X button but steel, no picture saves as i crop it.

this is the details of everything i’m using:
PHP Version 5.3.3-7
Wordpress: 3.9.1
Manual Image Crop Version 1.05

libraries installed in my WP:
GD Support enabled
GD Version 2.0

Is there any chance you know what i’m doing wrong? or why it’s not working?
Thanks!!
