If it's not a loose screen, it's very possible, perhaps even likely,
that either the lens or camera will be damaged by forcing the lens off.
(BTW -- did you mention what brand of lens you've got? This is rare
w/Zuikos, but not impossible.)
If it's the index arm on the back of the lens that's on the wrong side
of the coupling ring, note that the ring is made of plastic and will
break before the metal arm on the back of the lens (unless you get lucky
and it happens to slip back over instead of hanging up). But the
aperture arm in the camera is stamped metal -- if it breaks before the
aperture stop-down lever on the back of the lens, woo-hoo! Major repair
bill!
And, yes, if you can get the shutter to stay open on "B", you CAN see
most of what's going on inside there -- I've done it dozens of times.
Try winding very quickly (instead of slowly) with your finger on the
release button -- doing it slowly may allow the shutter to release
before the B-lever engages to hold it open. Try it several times before
giving up, too.
The last method of holding the shutter open involves some risk so I
hesitate to to suggest it, but you might try this: do the slow wind/
shutter on "B"/ finger pressing on release button routine, but this time
as the curtain bar gets to the right of the focal aperture in back (the
rectangle where the photo is "taken"), _gently_ rest a finger on the
metal bar as it exits. Then, when the curtains begin to travel, gently
restrain them and carefully allow only the first curtain to travel --
hold the second curtain back "manually". Now you can see inside the
back.
The risk is that, by allowing "slack" in the curtain strings at either
end of the curtains, they may slip off their rollers. If they do, the
curtains will be askew or buckled, requiring removal of the front
casting for repair. That's easier than replacing the aperture stop-down
arm on the body, but not as hard as replacing the aperture ring -- it's
your call either way.
BTW -- your neighborhood camera store/shop may have no idea what needs
to be done -- try to find an Olympus specialist, OK?
