[OFF TOPIC]
When you have activated a script in the Plus! preferences, it will stay activated. Note that this is for the script execution only. Think of this as executing a program or stopping a program on your computer. Even if the program does nothing, it is still executing.
Scripts can have their own menu to be enabled and disabled, accessable thru the Plus! icon in the contact list or conversation menu or with the aid of commands. Though, "disabled" means the script will still be running as far as Plus! is concearned, it only wont perform its actions. Think of this enabling and disabling as turning on/off a feature of the program.
If you have further general scripting questions I'd suggest to read the official
Plus! Scripting Documentation as all this is actually off topic to this thread.
