Hi Steven, I think that this issue might have been resolved in 2.8.2. I would strongly recommend upgrading to 2.8.2. The API changes should be pretty isolated w.r.t 2.2 so porting should be quite straight forward and you'll get lots and lots of bug fixes as well as general improvements. And.. you'll be far easier to support as trying to remember little details of old code is beyond my meager brain is capable of.
