"Windows XP HE": Win XP Home?

When I've got my
screen saver set to "on resume, password protect" I get a message
that says:
Secure Windows Desktop Detected
This configuration is currently not supported

Likely meaning that the BOINC screen saver doesn't support password
protected resume...

So just pick a different screensaver and leave BOINC running.
