That last tutorial was definitely the best, but I am getting an 'unhandled exception' whenever I try to run it.
If I run command line I get a request for a passphrase which I have not set.
I was amused by this from the PDF:
". Implementation
Sudowin is a complex product that provides a simple
solution to an intricate problem. Luckily for the end-user,
implementing sudowin on a desktop is quite easy."
I am stumped and unless there is another way to protect a limited user on-line I do not wish to take up your valuable time here - thanks for the stuff so far. I revert, I'm afraid, to admin user.
