Well, I've tried to set it up so I only use one or max two libraries, but sometimes things go wrong and something I thought should have been in one runtime wasn't. Even given that, I've used everything out of one runtime, just one, and it stalled three times in a row and cold boots wouldn't help and defraging never has helped. I'm setting up a separate P 5 for a project on a portable and seeing if that will get me there-- only prob is I only have 512ram on the portable. Emily
