Thanks Eno
Just had a chance to check out your theory & it seems to be correct.
My next whinge is about the size of pictures.
This new format seems to put a post with a picture in a window within the post. If theirs a lot of text to go with the picture then some of it gets obscured to one side, this used to be okay on the old site but with this new site I find I have to scroll to below the picture to find the scroll bar so as to scroll to the right so I can finish reading the sentence, then scroll back to the bottom of the picture to scroll to the left so I can read the start of the next line, & so on & so on.
It makes reading text with pictures a real pain, so is their some easy way around this that I don't know?
