Help with Acrobat js created menu button

Question

I as using a short javascript which creates a menu button. The js script is in the correct Acrobat javascripts folder. I am using Acrobat Pro 8.1.2
var oButObjAddSigningPage =
{cName: "AddSignPage",
cEnable: "event.rc = (app.doc != null)",
cExec: "AddSigningPage()",
cLabel: "Add Signing Page",
cTooltext: "Add signing page to the current document"
try
    app.addToolButton(oButObjAddSigningPage);
}catch(e){console.println(e);}
The function AddSigningPage()" is in the same script file.
Problem: The button loads and displays correctly (greyed out) if Acrobat is launched. If a pfd file is then loaded the button comes alive and the function works OK .
But the button does not display at all if Acrobat is launched by clicking on a pdf file.
Help please.

The proper input to the "app.removeToolButton" function is the name of the toolbar button, not the object that was used to create it.  Try this:
app.removeToolButton("AddSignPage");
The very first thing you need to check for is the "Add-ons" toolbar.  After loading your document, and when the toolbar button doesn't show.  Right click on an empty portion of the Acrobat Toolbar to display a list of all the individual toobars.  Is there an Add-ons Toolbar Listed?  Is it checked?
To determine if your Folder level script was loaded and run, Test the function created in that script.
Run this from the console window
     AddSigningPage
The code for the function will be returned if is was defined.
To determine if your toolbar button was loaded, run this code from the console window.
var lst = app.listToolbarButtons()
for(var i=0;i<lst.length;i++){
  if(lst[i].cName == "JSAppToolBar")
    console.println(lst[i]);
the "JSAppToolBar" is the internal name of the "Add-ons" toolbar.
However, from what you have described it does look as if you've hit on a bug.  Probably a timing issue.  What are the characteristics of this file?
