Can't get a simple "app.execMenuItem("Save")" to function!

Hi all,

I have a simple script that flattens a page. It works well. I just want to add a command so that the document saves once the page has been flatten:

function Flatten(boolCurrentPageOnly) // Takes a boolean argument { if (boolCurrentPageOnly)                          // Flatten either this page...    {    this.flattenPages(this.pageNum);     app.execMenuItem("Save")                    //That's where I inserted  the new command. All works fine otherwise. Except that it doesn't save  the doc.    } else    {    this.flattenPages();                                 // ...or all pages    app.execMenuItem("Save")                    //That's where I inserted  the new command. All works fine otherwise. Except that it doesn't save  the doc.    } } //Installs the menu app.addMenuItem({    cName: "Flatten current page",    cParent: "Document",    cExec: "Flatten(true)"}); app.addMenuItem({   cName: "Flatten all pages",   cParent: "Document",   cExec: "Flatten(false)"});

Anything I am doing wrong?

I am on Acrobat 9.

Thanks!

app.execMenuItem("Save")
