iMac webcam

it won't work with stickam and I have yet to try it with aim video chat.
it does work with the myspace webcam thing.

what should i do?

I know there is a lot of 3rd party software to make your webcam more universal. I'm pretty sure it works with aim video chat. As for stickam, I have heard that you need to have the correct browser flash plug-in for it to work correctly, so make sure you have the correct one. Sorry if I wasn't much help, I don't know too much about all that webcam stuff. Good Luck!
