problems with online/offline...help!!

my biggest problem is that spacehey always has me as online, even when i'm logged out everywhere.  i have a custom online icon, so i'm not sure if that has anything to do with it.  i tried adding a code for a custom offline icon, but it doesn't work, even when i manually hide my online status.  i'm clueless at css, so i basically went into my layout code, found the code for the custom online icon, changed .online to .offline, wrapped it in style...aaaand nothing.  can someone help??
