I am having difficulties setting up customactions within our website.

First question:

What is the amount time it takes for a setting change to be applied? I have noticed that when disabling a rule the change won't become active for a period of time. This makes it difficult to be aware if a change within a rule's setting is applied or not.

Second question:

When a trigger is invoked via a customaction, does it only apply to the single rule or does it go through the list of rules and applies the first applicable rule.
