What version of FileMaker?
Just ran a quick test on Windows 7, FMP 13 where I had a file already set up with a limited password and I could not get into find mode on a limited access password. Neither ctrl-L nor from the View menu.
FM14 on Mac.
Is it a script that runs from a custom menu item Or is it a system command from a default menu.
you should at the very least circumvent it by using custom menus and calculate whether it is to show based on the current privilege set name
