Yes, I thought so. I wonder what causes this problem, and why it is that some people have it at some times, but not everyone every time. What could this be the function of? Is there anything in common between those who have the problem at any given time? I don't know if finding that out would be a way to avoid it - I doubt it - but I am wondering anyway. It can't be anything so simple as the country one is in, since someone (I forget who) said not long ago that it was possible to log in on a different account on the same computer. And since it's not always the same people - I know that much, because for example last time I didn't get this problem, and now I do -, I think it's probably not something entirely static.
