When using Win XP Pro SP1 and the screensaver is PW protected, I get a function not supported error and Seti does not run.

I think nobody tries this out in the Alpha or Beta test group.
This function was very probably not of high priority therefore it has not been implemented.
If you would like to see it working, please post it under the "Wish list".

It is a known issue which needs to be solved in the future. There is a problem how BOINC screen server is working and how Microsoft - since some Window releases - want a screen saver with passwort to work.

It is a greater problem then it seems to be at first and the core team developers didn't find a working solution until now. Maybe there must be done more changes on the design then they want to do at the moment.

But different to the old SETI@home Classic GUI, the SETI@home BOINC GUI didn't need to work as Screen saver. If you need to protect your host by password, you may select a different screensaver, at the best one, not using graphics, that only shut down the screeen and give the password protection.
