MS Access Security

The below code is about security. I am disabling the tool bars if user belongs to the user group and enabling them if belongs to admins group. And I disabled F11 and shift key both irrespective of the user group. But one drawback of disabling F11 is it disables the mouse right click. if the F11 is disabled , the right click no longer works. But i added code for  the right click to work( which is on the Case "Users"). But i am not sure whether it is foolproof or not, because i got to know that on some system the right click is working and on some systemm , its not working

The other question is I would lke to disable ribbon in 2007 version , i feel the below code is working good for 2003 version of access but in 2007 there is ribbon. retaining the same below code , i need a code which disables the ribbon in ms access 2007.

I tried Docmd.showtoolbar "Ribbon" ,acToolbarNo. But i do not know some times it works and some times it does not . Do i have to be sure about the order of statements i execute in the code .

I need to disable ribbon, navigation pane and at the top the office options in 2007 So i add the code to disable all the above things. then i should not modify the code based on the version. you see. i want the same code to work on access version 2003 or above. So Please Help me .
