Didn't read the other thread, as i am in kind of a rush. Did you report this to DAZ? I have something related happening, but it hasn't bothered me quite so much, so I didn't think much about it until I read your thread. When I load a library file, I get the hourglass for a second or two, and then it goes away...file finishes loading later, as you said. Odd. Haven't taken notice yet if this is only in external runtimes or in P6 as well, since I haven't used the P6 runtime alot. May have to go take a closer look at it.
