I was having some problems with Chrome at the weekend. First it denied me access to the Guardian website (this was on Friday, I think), saying that the website "sent an invalid response". It was OK by Saturday but that evening I got the same thing when I tried to go on Pubs Galore. I've been away for a few days and it was still the same when I got in this evening. I tried Internet Explorer and got a similar reaction.

I am writing this from my laptop, where I use Firefox. So, are other Chrome users having the same problem, or is it just me? And how do I fix it (apart from using Firefox on my PC too)?
