Seems like rules are tied to s/w resources as I never noticed the following informational bar while editing a rule. However, I saw this text while creating the detection rule for the first s/w resource I was creating. I wonder if this is because I might've named it exactly the same as the old one so Altiris thinks it's tied to an existing s/w resource?
"This rule is associated with multiple software resources, and any edits to the rule may affect the detection or applicabilty for those software resources."
