Not sure what a wingover is,at least not in terms of canopy flight,but i did just what you described under my old Sabre 170.It turned instantly into 5 line twists and i just about sh@t myself.Not sure if i was just unlucky or very stupid,still it was a lesson learned.
Is it when you stall the canopy and suddenly let go of one of the toggles?
Never let go of a toggle. Never let go of a toggle. Do not let go of your toggles. Letting go of the toggles is bad.
You use your toggles to steer and brake your parachute, when you let go of a toggle are you certain you'll be able to get it back immediatly if necessary? Please, for your safety and the safety of those around you keep your hands on the toggles and your head on a swivel.
I know a "wing-over" as pendulum type manuver that swings you over the top of the canopy, kinda like a loop. It's accomplished by alternating toggles. Your path is like tracing a mobius strip. If the G force is high enough you will invert and not fall into the canopy. A fellow from my DZ did it with my HeatWave at a 1:1 loading. He went to the apex, the canopy collapsed and he fell off to one side of the bottom of the canopy. Luckily it cleared, but it was a very low pull. I personally haven't done it under canopy, but as a former pilot I would pull the nose high and use rudder to kick the plane over (like going into a spin) then neutralize with opposite rudder. It was like doing a cartwheel.
Skydiving is not a static excercise with discrete predictability...
I did something like that (the pendulum type manuver) jumping a couple weeks ago. I had pulled a bit higher then usual (I was in the saddle at about 3.5k) so I thought I would play. I pulled the right toggle to start a good ol' spiral, at about the top of the swing to the left, I pulled the left toggle fairly quickly to swing me the other way (trying to get a real fast dive/turn/spiral). Well, it started very well and then my canopy collapsed in on it's self and my lines twisted. Luckly for me, the canopy started to spin and dive (sarcasm), but a couple pulls on the rear risers and the canopy fixed its self (right before I cut away). After all of this I had lost 1k of altitude, atleast I was still at 2k, though.
Well, until my canopy went to crap, it was pretty cool, I was in a pretty steep dive and starting a turn real fast. I don't think I'm going to try that again, atleast not like, though.

It's in the new ISP and four are required for an A.
I started doing them on jump 12 or so and fell in love. I have had to look up and to the right to see the ground. (if someone can go further inverted, be my guest. I won't.) I have not had a collapse yet, I think due to easy toggle input both going in and coming out. I usually hit the transition rather quickly but never hold the thing for more than a 180. I have felt the rapid deceleration at about 150 degrees that told me I was going to leave that apex involuntarily if I didn't ease out of it soon. It is super cool if done correctly. I know on my Silhouette at 1.1, I can not turn a reverse canopy turn into a spiral. There's just too much inversion/momentum loss happening to translate into a spiral, for me at least.
Exactly Ramon. He may also be confusing a wing over with a barrel roll, where you dive, pull out of it and do a 360 towards the horizon, going inverted and coming back to level flight towards the horizon again on the same heading as the climb was initiated.
