The Mecaplex sliding window on my ASW 24 emits a loud whistle while in
the closed position, at all airspeeds.
The noise can be made to go away if I press firmly outward at the
trailing edge of the sliding window.

After a while it is so bothersome as to give me a headache. I have
tried stuffing a piece of paper towel in between canopy and window and
this will quiet the noise for the rest of the flight.

Note this canopy is a replacement, not original equipment.

Any ideas for a permanent fix would be appreciated.

Dan;
Your flights are simply too long. A fellow like you (old hang glider
guy) shouldn't need more than 20-30 minutes in the air - max. Stop
worrying about the OLC - most of us can't get the daily results to
come up anyway. Any old dangle diver dude should also know the real
solution is duct tape. Don't just cover up the offending opening with
the magic elixir tape, but get most of the canopy too. This will keep
the sun off of you, and the less you see, the less you will worry
about. Headache will be gone.
