OK, so the initializatio is hanging, not the application itself; it wasn't clear to me from your posts that Mozilla was not even loading, only that it was hanging (which to me means that it's running and then it stops running). I'd like to make the same suggestions with regard to Java* and not moving the mouse or typing at all while it's tring to load. That's probably not doing to make it work, but it will give us some information: it will say that it's not a user event that caused the problem. Another thing you might try is to cause Xevents to be synchronous (this is a debug option, eiher via libX11, or in the X server startup). I'd also like to make the same suggestion with regard to the threads scheduling, to see if it's a bad asumption in the mozilla code about object or code reentrancy being protected against preemption. The reason I'd like to see this is that, as you point out, it works fine with libthr, which has this assumption, at least on UP machines. I'd also like to see someone with an SMP box using libthr who has a problem with Mozilla... ;^)... but that can wait, I guess. -- Terry
