Mark, With all due respect, I don't read every single post to the LUG and it is reasonable to expect that not everyone else does either. I have no intention of rehashing the debate of a couple of weeks ago, but the results described are consistent with developer exhaustion so I thought it was worth pointing out the Kodak link. Is that rude? I don't think so. Obviously, the original poster is free to digest all available information and draw his own conclusions. Equally obviously, *something* went wrong in his case.
