I didn't run your program but I did notice that many of your rules
are dependent on an absence of a 'repair' fact. Since you appear to
retract the repair fact, these rules will fire again. You should
'watch rules' or 'watch all' to see what is happening ... it will 
tell you exactly why the rules are being put back on the agenda.

Subject: JESS: retract doesn't work like I want it to do

Hello everybody,

I need a hint from you. When I try to retract a fact, all other facts are 
reactivated. To understand what I mean, I'm sending the "anlageneu.clp" and 
"fehlertabelle.dat" with this mail. It has a small GUI and it's asking some 
questions to the user. Answer the first question with "expertensystem", the 
second with "ja" and the third with "nein". This procedure will insert the 
following facts to the working memory:
(Zylinder IO)
(Funktion Probleme)
(Notausschalter unbetaetigt)
(repair "Jeder Notaus- Knopf muss unbetaetigt sein. Loesen Sie alle, die noch 
gedrueckt sind!")

In the next step I have to retract the last fact to fire the rule 
"reparatur_Schutztuere_Stufe1", but it restarts questioning the user with the 
first three questions. Can somebody tell me what's wrong with the code?

Best regards,
