Toolbar Buttons Not Showing By Default

Hi - I want to create a custom toolbar button with an image. I can do it fine, but I can't get it to display without having to manually turn on the add-on toolbar.

the issue is that when I create the toolbar item, I do it in a folder level javascript.
There is no presently open document when that loads (I don't think) and so I am forced to go through the work around described in the api book of creating a new temporary document, importing the icon, and then getting the icon stream from that document, and finally building the icon.

The problems - 1. This is a long process (even though it is a small image) and 2. Because I do it on a temp doc (I guess) and then close that doc - the add-on toolbar is not turned on when I get to my real document.

So I was wondering two things -
1. Can I store that icon stream in the file as the hex-encoded string and then just load that - to save time.

2 (and more importantly) - How do I turn on the add-on toolbar by default or at least have it on for when my document opens.

Any help would be greatly appreciated.

Below is my script - it is essentially a copy of what is in the api. It is being loaded from the program JS folder:

var buildToolBar = app.trustedFunction(function(){

app.beginPriv();
var doc = app.newDoc();
doc.importIcon("formtool","/C/Program Files/Adobe/Acrobat 8.0/Acrobat/Javascripts/formtool.png",0)
var oIcon = util.iconStreamFromIcon(doc.getIcon("formtool"))
doc.closeDoc(true);

app.addToolButton({
cName: "formtool",
oIcon: oIcon,
cExec:"execToolMenu(this)",
cEnable:true,
nPos:0,
cLabel: "My Form Tool"
})
app.endPriv();
})

buildToolBar();
