I'm a now a proud MoI owner!

 From:  stinkie
So I guess it's time for my first daft question. I'm going through the lamp tut (which I'm enjoying a lot - thanks to it's maker), and - hey! - I ran into a little problem.

I cannot put a fillet around the lamp button. As this is my first MoI model, I'm probably overlooking something obvious - but of course I have no idea what. (It's not the radius, though. At least, I don't think so.)

Any help will be greatly appreciated.
