The problem is that no link with a button inside* will work in IE6 nor in IE7. Now I wonder if there's some simple HTML trick to fix this or if I need to rely on JavaScript or CSS (to reformat my buttons/links) to fix this issue.
(*Hopes that somebody visits this forum in the next few years*)
* Code example:
<a href="http://blablabla.bla" title="blabla"><input type="button" value="Click me!" /></a>
