Fast user switching (log off)

[Frenzy]

Im havin a problem with my mums pc, for some reason it wont allow the log off-switch user. Ive been to user account in control panel and ticked the 'use fast user swithing' but when i choose apply options it wont save it. im takin a guess at it bein another setting or registry entry. Anyone got any ideas??
