I've noticed that when I quote something, by using block-quotes, e.g.
the subsequent paragraphs don't display correctly under Internet Explorer-. They are fine with Firefox. I suppose I should look into at some stage. Alas, the only time I have is at home, and their I don't use Microsoft… So it might have to wait until the next time I work during the weekend (which should be a long time away).
I've fixed it.
Alas, Internet Explorer doesn't handle having a left border and no right border well. Removing the borders and colouring the blockquote gets around the problem. I found this by accident.
