Thanks for the suggestion.
In fact the preference file is accessed by the limewire everytime you open it. Artificially locking it does not work. Limewire itself should require a password to open the preference file (an administrator password, as many applications do) So simple that I do not understand why they did not.

And a log of the downloads should also be a minor challange to introduce in the application.

it seems they are not interested, but it should interest many users ..

Let's see if other ideas surface
