Thanks for replies, I did wonder whether it's a virus.
A link that doesn't work for me is on post 1 on the Banksy thread in JB. I did try right clicking and open in a new window but it didn't work. No real sweat really, just went to the site direct. Curious if that link works for some people and not for others.
As Keef says, I get by...just an annoyance.
