YES!
I thought I was the only one. I just put it down to being a kook at the time and tried to forget it, but I actually had the kite up and flying for a couple of minutes before the first bit of strain popped it off. Again, a small knot and not much holding it on there, but I instinctively give them all a yank now after I put them on every time.
No damage, no injury, just my pride dented.
More experience shared, power to the people....
