Yep. That's it exactly. I think the portable dumper's supposed to fix this problem - but I've never actually tried using it (or needed to use it) so I don't know for certain. [from the other e-mail] Yep. But silently dying is much much worse, because it leaves people with the impression that the program doesn't work at all, whereas in reality, it just doesn't work when built on someone else's machine. Don't hold your breath. It looked to me like your memory region wasn't part of a module (i.e. DLL or EXE) - but it could still work I suppose. I'm not entirely certain that what I did in that patch is safe, which is why it's "experimental"; I think it probably is, but it's certainly undocumented... Kind regards, Alastair. ____________________________________________________________ Alastair Houghton ajhoughton(a)lineone.net
