[SOLVED] Links showing as crossed through text

Wonder if someone can help with a weird problem. I've used Atahualpa on half a dozen sites now and never had this happen!

Onfront page of my site I have a few links going to other pages on the site. The links are all showing crossed through. I ahven't changed any settings that would affect this, as far as I know, and just can't work out how to take the cossed through effect away.

The site is www.jetstreamconsultancy.co.uk

Any help much appreciated! Thanks
