i wasn't sure where to put this. it's sort of a bug, but only if you care if your pages are generating valid xhtml. i suppose it could also be a feature request.
while testing 1.2.7 with my theme i saw that pages weren't validating if there was a $css_class_active printed in the menu. looking at the code i saw that it was printing something like:
`<a class='activeclass'href='address'>`
with a double space after the a and no space between the class and the address. after changing the beginning of lines 197 and 199 of print_album_menu.php from:
`$link = "<li><a ".$current."href='"`...
to:
`$link = "<li><a".$current." href='"`...
the page validated. thought i'd post it in case it helps anyone.
(i edited this post to keep it from being too wide. there is more to those lines.)
