OK, that wasn't it, either. The _first_ time I do it, namely (progn (setq debug-on-quit t) (signal 'quit nil) ) it brings up the *Backtrace* buffer. Second time and forever after, it is just "Quit" in the echo area. The same actually for any error: for example, (message 'not-a-string) - first time the buffer, thereafter a message saying: eval: Wrong type argument: stringp, not-a-string So the error doesn't have to be the same. Only the first gets the backtrace. Even with `M-x debug' (which shows the backtrace buffer), the new error(s) doesn't seem to be documented there. Isn't there like an *Errors* buffer were only error messages gets stored, and all of them? -- underground experts united
