[Plugin: Sensitive Tag Cloud] Exclude current query tags not working

hi there people!
‘Exclude current query tags’ its not working for me. im using wp2.8.2

i think i’ve found what is working wrong.
i write my tags names Capitalized and there are ones with more than 1 word, and WP transform it for the slug all in lowercase and add ‘-’ for the ones with more than 1 word.
so i was looking at the code:

// exclude tags
if( !in_array($tag,$options[’excludetags’]) ){ // only if not excluded

the $tag value here is the name ie.:’Black Hoodies’
and $options[’excludetags’] have the slug ‘black-hoodies’

as in_array() is case sensitive… never match.

i’ve found this playing arround, and i dont know how to make it work.

any ideas?
thanks
