Ok thanks guys, I will have to play around with it a bit more and see what I can come up with.

It's really weird as I used to use my iphone for GW all the time and it kept me signed in up until last week (I think). I have never had any issues prior to that and posted mostly from my phone.

I've tried deleting my history and downloaded the google chrome app to see if that would help but they all won't let me sign in
