On the way to the airport, the window in the van started opening, being fully open by the time I got there. I pulled the inner stuff off, but I don't have a clue what I'm looking at, so I just put a zip tie around it to hopefully hold it closed.
I noticed that one of the wheels is leaking a little brake fluid, suggesting I didn't do the greatest job of installing the new O rings. Despite this, I took the Magni out for just over an hour, and got bounced around a bit. When I got back, I spoke to Tony, and he'd had the crap kicked out of him in his Just Summit and Cessna, so I felt better about it :o)
At home, I took a look at the window regulator in the van, and I need to take it out and get a look at it. There are all manner of things that could be wrong, and some are easy to fix, and some will require a new regulator. Bah.
