Assuming you are such a 'savy professional' 'Mr' Jones, why didn't you notice throwing memory at the problem doesn't help? On another note: If you think *you* know better, why don't you contribute a *working* example of the Burleson strategy? You have a track record of lurking and only chiming in when you can flame someone with the drivel like you posted above. I recall your flame wars with Daniel Morgan, which only served to establish *you* are NOT a 'savy professional' but just some *arrogant idiot* (of which we have already way too many here).
