Ok, seems that I've finally tracked down the problem.
As I stated in my previous post, if I remove the charset=UTF-8 meta tag from the header, links work as expected (always). So, after trying a bunch of impossible things, it turns out that my header.php file, even though it was encoded in UTF8, it had no signature. You know, the famous FF FE codes!
I don't know why this was causing so much trouble to IE6. Note that every other browser including IE7 had no problems with this.
Thank you very much for your support on this!
Regards,
Jose
