Hi, that is a new and strange behaviour, because Plot[a*Sin[x], {x, 0, Pi}] will copy the messages in your notbeook Plot::plnr: a\Sin[x] is not a machine-size real number at x = \ 1.308996938995747`*^-7. and what stand a the begin of the message ?? "Plot::plnr" does this eventual mean, that the function Plot[] had generated the message ?? When you write you own function like myFunction::bad = "This is bad" myFunction[x_] := If[x > 1, Message[myFunction::bad]; x, x] the message is placed in your notbeook and it is up to you, to find out that "myFunction::bad" is a message from myFunction.
