Ok... i realize that... 

I did that though I get a nice set of garbage for the output again...

I've attached my code and fiddled every which way to no avail so this
technique doesn't seem to work... (this is solely ui code no network
stuff)... Is my design completly off or something... ??? (arghghg this is
frustrating:P in an interesting way though).
