Thanks all for the suggestions.
Chris's suggestion looked favourite as I could have that in my own
stylesheets to over-ride the theme css so it doesn't break if I
update, but for some reason wasn't successful. But Richard's change in

I can confirm this was the problem. My tab widget was in a jquery ui
dialog widget. The css class that describes widget (not sure exactly

size to 1.3 em. Therefore the inner tab control was being set to 1.3 *
1.3.
Adding a css lin
I've hit upon a similar problem where a page I have added a tab
control to now has much larger fonts. I believe it's to do with the
fact that tabs use "em" sizes and so does the element I've place the
tab in. I believe a bit of CSS modification will do the trick.
