Thank you for your help guys.
I am not sure what i did but its now saving my selected cookies.
I deleted all cookies, saved and unsaved so the lists were blank. I then logged on to the dozen of so sites i wanted to remember me, then went back to my new cookie list in CC and re saved the ones i wanted, deleted the others and now it works OK !!
It could be that i needed to do that having downloaded the latest version ,22-2 968 of CC. The new version could be the fix but you need to re do your lists after down load ??
If it happens again after a update download at least now i know what to try first
Many thanks
