Hiding Commandbars For Worksheet

I want to hide the command bars for the instance of XCEL that I am using. DO NOT want to hide them for the application.

I have this working at the application level with Application.commandbars ... but the problem is that if I open up another instance of XCEL at the same time... there are no menus available.

I have not been able to get Thisworkbook.commandbars to work. I assume this would keep the hiding of the menus to the instance of the workbook I am using but this does not seem to work.

ANY IDEAS? Thanks in Advance !!!!!!
