Hi Steve, no I don't but that site doesn't have a decent start page yet so I've set it to forwards automatically to the next page, which is my web shop. Maybe some browsers pick this up as a problem if the security settings are set very high? I've had it like this for almost a decade and you're the first to mention it. But it might explain why I'm selling hardly any prints, haha!
In any case, I see I need to update my links anyway as one is dead and the digitalaviationart one is replaced with another site, so thanks for bringing my sig to my attention
