Yeah, and we have yet to leave it. I have had to educate on it twice 
only last week.

But OK, then I know.

Ah. Been there, done that, prepared option for higher resolution but 
ended up not having time and need to dig deeper in that product.

Me being obnoxious I kept doing these designs inhouse because what we where doing was not fitting a standard scheme. We still do not match that, even if I do a standard out of what we have done. Ah well, the other way around. :)
