wpCAS doesn't work with multisite

I’m trying to set up wpcas on my new multisite.

i activated it first for the entire network but wpcas was telling me that it wasn’t set up on a particular blog. i then went in and tried to activate the plugin for individual blogs when i noticed that it wasn’t letting me update the wpcas information for the individual blogs. whenever i hit the update options button it switches me back to the root level blog rather than updating the options for the blog i’m currently in.

i haven’t delved into the code yet to see if i can fix it, i thought i would turn to the forums first and see if anyone else had run into this and fixed the problem.
