Yeah. That's the normal way to work for a Smalltalk debugger.

I remember once debugging a thread without killing it. I've asked a customer to click on a link that would get to a bug while having remotely opened the IDE that was serving that user session, setting a conditional halt. Seen it halting, fixing the bug and saving the method with the halt removed and let the thread run. All the user saw was a long request that ended in service instead of that bug.

I don't see any "running backwards" mentioned in this story. I'm familiar with "break, fix, restart" debugging from Lisp (which had a lot of cross-pollination with smalltalk)
