there was another error, the .zip was updated again.
for those who installed prior to this message (v1.1), in cp_forums_cats.pl (template) find
if ($cathastyle) {
replace for
if ($cathastyle eq $num) {
and thats it. this was placing a "selected" parameter in all options of the style select box in the category settings, making the last style selected in all categories that had one. fixed now.
