All I could figure was that the sound was good enough to put up with the hassle. A strap is about the only solution I could think of, but I don't like using one. I never tried the thin body type either.

I found the problem wasn't so bad when playing it, but rather when you stop between takes. I'll tend to rest my right arm on the top of the guitar and lean on it. Just when ya least expect it... whoosh, it goes flying.
