Here's what we have tried:
If possible, we would like to just disabled the 'File' section that can be dragged around altogether, however since this save button is the only remaining button on that section just the code to disable it will work too.
Also, I'm not asking to disable it, just simply hide it as if you were to right click on it, go into show/hide toolbars, and click 'File'. We have many kiosks and doing this manually would be... Well I got a life to live.
P.S: I forgot to mention. If I open Adobe Reader standalone, the button is gone. If I open it through IE the button is present. It might be because the file is already on the computer but.. I don't know. Thank you!
