After even further thought, I'm a little surprised that the debugger wouldn't have removed that breakpoint when it stopped, thus causing memory to match what it was displaying as what should be there, although, at the same time, I'm happy it didn't, because if it did I wouldn't have been able to read it with the external program and (eventually) see what was happening to me... So that, I suppose, might still be considered an IDE/debugger bug, as its left a process image in a state other than what it displays, but I suppose that can be considered the prerogative of the debugger, and maybe even, at least in this case, a good thing. Perhaps it treats the traps of coded int 3's differently from the breakpoints it sets, in this regard (or not - but right now I don't feel like trying to figure that out.)
