Hi esmi,
Thanks for that answer. I'm sure you're right about the child themes business. People seem to think it's hard, but in fact one of WP's great advantages IMNSHO is that it's so easy, to create a child theme. And please keep adding your comment every time I forget to remind people to use a child. It's a public service :-)
Anyway, mustn't hijack the thread, must I.
As for IE, yes, that's what I understood. I thought tdillon2011 should be aware before believing the problem solved when it's only solved for proper^H^H^H^H^H^H non-IE browsers. The hack you're referring to is this one, I guess? That's what I've used in the past, anyway.
Cheers
