when it freezes, it freezes on showpage(), so all the calulations etc are already done but from somereason showpage turns into a endless loop

Buckerman, I think you hit the nail on the head. That's ingenious. I don't know if it's causing it, but I did indeed change the order of the hook functions in the last release. I have no idea if that is what is causing it, but it's very possible that my computer is JUST fast enough to process the particles before it goes into an infinite loop. If that is the case, changing MAXNUMPARTICLES to a lower number like 1000 probably WOULD fix it for someone's computer. Probably, setting it to a number like 300 would be better. If you have a faster computer, the autolimiter will automatically raise it to a prettier level. I don't think there is a computer that can run verge3 that would not be able to process that amount of particles. Also, one of the contributing factors is also that I chose one of the slower, computationally speaking, demos to start with.

Again, thank you, all-powerful-one.
