Spider cracks in windows

I have noticed some small cracks on the inside of a window behind the catches  is their any repair apart from new Windows, Bazz .

They come as a non-optional extra Bazz.  

I wouldn't worry too much unless they grow noticeably. Ours were probably cracked from new but I didn't notice. Some ham fisted eejit tightened up the screws too much I expect, but I'll wait until (if) they get serious before shelling out a lot of cash for a new window.
