Thanks for your reply.
Previously, when I was logging in as a limited user, Password Safe was not listed in my Programs menu and there were no icons for it in either my system tray or on my desktop.
So, I found the excecutable file in the Password Safe sub-folder of Program Files and opened the program from there. Yes, I should have thought of doing that before I posted previoisly!
I now find, as a limited user, that I have tell the program where the password database is stored (when I am logged in as Adminstrator, the program has already selected this file at the log in stage).
Having keyed in the password, I am confronted with 'Yes', 'No' and 'Cancel' buttons and the message:
Open the database for:
read only (Yes),
read-write (No), or
exit (Cancel)
Note: Choose "No" only if you are certain that the file is not being used by anyone else, including another copy running on your machine.
At the moment, I am choosing to open the database in read-write form when logged in as a limited user (even though I would not be similtaneously logged in as Adminstrator), meaning that I don't have all the flexibility I would like, but I can live with this right now.
