Right...looks like rolling this stuff off onto a separate thread will be easiest (btw, the thing I'm doing is running a loop walking down the tree of an XML doc...so I think it's easier to just keep it all in one step rather than breaking it up).
Now does anyone have answers to my keychain question (in another thread) ? ;)
