I had the same problem, but the following method solved it. Go to an arts and crafts store and buy two inexpensive items:
#1: A set of split rings, like the type used on a keychain. The smaller the better - the ones I use are about 1/2 inch across.
#2: Some small metal spring snaps; the type with the little metal bridge you can push in and out. Thread your strap properly, attach it to the snap, and attach the split rings to your camera. Then hook and unhook the strap whenever needed. That way, attaching and removing the strap takes only seconds, and you don't have to unravel the strap each time. I house my Oly in a PT-018, which doesn't interfere with the rings being attached.
I've attached a picture of my camera setup. Hopefully it will help show what I'm talking about.
