Chrome, but not the colour

I'm still down in France, and have found that every time I tried to add a comment, using my Ipad, when logged in via Chrome my screen would flip to the iTunes shop page.  I hope you couldn't hear the language I was using every time!  So frustrating.  I've at last found that if I go in direct from Google then I don't get the same problem.  So now I can go and comment on all the lovely work on display without swearing.
