Hi,
I don't understand why I sometimes get an unreadable feedback when calling
trace/1. And then suddenly, the 'normal' feedback returns when next I call
trace/1 again. This doesn't happen to me in previous Pl-versions. What I get
(in 3.3.0) is:

?- trace.
Message: trace_mode(on).
Message: frame(128,call,[])
 ?

What I want (like in 3.2.8) is:

?- trace.

Yes
[trace] ?-
