nextgen-gallery ESC key not working

Hi,

I’m using nextgen-gallery and noticed this problem: when I click on a picture and it appears in the lightbox, if I press the “ESC” key I don’t go back to the page. I have to click on the picture.

This on my opinion is a lack as I also noticed other threads speaking about “click here or press the ESC key”. Pressing the ESC key actually doesn’t work (tried with both IE and Firefox).

Probably there is just a .js file to edit, I haven’t yet found it.

Can you help? Would be much appreciated. Thank you!
