LightBringer,
I've had that problem with the screen hanging for a split second with some 'set' commands. I'm afraight there is nothing you can do about it.
Prophetus,
the TL delay, that you're talking about, has probably to do with online lag, right?! Offline, it fires instantly. But offline it is delayed by the ping time. This is one of the most severe disadvantages for HPBs ... they can't t/l really fast.
