Supporter-write.php ("new post" still showing in two places)

hello,

everything is running great and looks like my "errors" bad luck streak has ended...

only thing is i have supporter-write.php installed in /mu-plugins/ and it does remove "add new" from the area below "posts" but if you click on "posts" there is still an "add new" button at the top of the page in two places.

can this be fixed easily?

thanks in advance,
gina
