Yes, I thought you said it was Vivaldi, so I've just checked the site out using it but no luck. By luck I mean getting the same problems.

My smileys are also above the reply box rather than to the left, which is confusing.

I remember you telling me about the stacked images, but I was kind of hoping that the fact you hadn't mentioned it again meant it had gone away.

Do you know anybody else who uses a Mac, and could you ask them if they get the stacked images? I might have access to a Mac briefly next week so I'll to sneak a look.
