problema: quando clicco con il tasto destro sul desktop l'unico risultato che ottengo è la clessidrina come se il pc pensasse. in realtà, credo, non accade nulla. se apro il task manager non ci sono processi particolari oltre al ciclo ide del sistema, la cpu è al 4-7%, ma se trascino la finestra del task manager mi si moltiplica come fosse sovrapposta. ho xp he tutto aggiornato, antivirus avg free che non mi segnala la presenza di virus. Ho fatto una scansione con hijackthis di cui posto il logfile:

Come mi debbo muovere, perché ogni tanto mi piace cambiare aspetto al sistema, allo sfondo, e screensaver.
Grazie e buon fine settimana a tutti
