Coincidentally, I just filed an RFE on this very topic (something I'd been meaning to do for a while, but forgot about until I upgraded to 1.33.0). It was suggested to me that I mention it here. Actually, I'd have posted here, in the first place, but it seems I misunderstood the prerequisites for joining this list (I thought it was for code contributors, only). From the archive, I can see this thread has covered most, if not all, of my points. Still, my RFE is probably more cohesive than any single message, on this topic, I've come across in the archives: http://sourceforge.net/tracker/index.php?func=detail&aid=1274707&group_id=7586&atid=357586 BTW, I really don't understand this continual talk of a user-supplied/overridable handler function. It still compromises debugging, and without managing to provide anything the user can't already do in the user-supplied threadfunc. (I'm only mentioning this because it's a proposal not addressed in my RFE.) Thanks for considering my views. Matt Gruenke Software Engineer IntelliVid Corp.
