David, try yardenman's suggestion -- having a really clear reflection in an actual mirror to deal with might well distract him from the less distinct window reflections. Inside lights could also help by making the interior more visible than his reflection. Good ideas, and easier to try then draping all the windows LOL.
Carol, I've seen seed feeders that were like a tube feeder inside a globe of widely spaced wires, meant for keeping big birds out while permitting songbirds to eat... I wonder if there's something you could rig around your feeder like that? It would need to be big enough that a 'coon's reaching arm couldn't quite get to the suet, though, and that could be pretty big.
I know some people mount their suet feeders to the underside of a board, so the starlings don't steal the suet... what if you did that but used a fairly big piece of wood, so a raccoon could sit on top but wouldn't be able to reach around to feeder on the other side? I have a feeling one of those half-dome "squirrel baffles" wouldn't deter your visitor for more than a minute.
Once an animal has found a food source like that, they'll do a lot to continue getting it -- a block of suet is a big reward. It sure would be entertaining if you could put up a security camera to get video of your varmint's efforts to get around your attempts to foil him...
