I found something that works for me. There is an option in the login options that allows you to use fast user switching. (I am the only one on my computer but) I am using this as the method to lock my computer. I just let the screensaver/powersave options kick in on their own. Doesn't solve the initial problem but does allow me to quickly lock my screen when I walk away from my computer. 2 clicks of the mouse and your there. Here's the link for whoever is interested.

EDIT-> INterestingly enough I found out if you just let the screensaver come on by itself, the normal lock function works. - Just an FYI
