I hear that.
The non-blocking, single threaded, asynchronous data calls nature of Flex takes a bit of getting used to. OT, Laurence, I am nearly a neighbor. I live in Carrollton, and am currently commuting to Alpharetta 3-4 days a week.

Yeah, that's what I thought.... Ugh... That means re-writing a bunch of code just to add a damn Yes/No choice for the user... Not fun... I just with the bosses would stop wanting stuff changed!!
