Quote - A new oddity I noticed - I'm running the script from a very simple poser file:

{
version
    {
    number 6
    }
runPythonScript ":Runtime:Python:poserScripts:3DCheapskate:PropGoto.py"
}

If I make this file a pp2 in the Props folder it runs fine. But if I make it a pz2 in the Pose folder it runs twice every time! Can't figure that one out.

Try using this syntax:

{

version
    {
    number 6
    }
}
{
version
    {
    number 6
    }
runPythonScript :Runtime:Python:poserScripts:ScriptsMenu:NameOfScript.py
}

Don't know why it works, but it does.
