100 Canon Macro w/extender?

I just got my 100 macro and when trying to attach either of my Canon extenders the little screw on the lens mount prevents me from attaching the lens. The lens instructions says that it cannot be used with Extender EF 1.4 or 2X. Yet I have seen many picture posts that say Canon 100 macro w/1.4 or 2x extender. What's up?

Hey Don,
No, I am refering to the tele extenders. I am able to use the extender if I put an extension tube on the body first. I would like to be able to use the 1.4 extender without the extension tube.
Anyone know if I can just remove that little screw on the lens?
