That approach is dependant on the screen saver executable actually doing
what it is supposed to be doing - notifying the OS that the screen saver is
running.  On NT-based systems, at least, a more reliable approach would be
to use OpenDesktop() to see if the "Screen-saver" desktop is actually
running.  Do note, however, that there is a known bug in NT 4.0 SP4:

    BUG: OpenDesktop ("screen-saver",...) Returns a Valid Handle When the
Screen Saver Is Not Running

Use OpenDesktop() to open the "WinLogin" desktop.  In case WinLogin
continues to exist while the user is working, you may have to use
OpenInputDesktop() instead and then use GetUserObjectInformation() to see if
the active desktop's name is "WinLogin".
