I use windows XP and these last few days I have discovered that my screensaver remains unactivated even after the lapse of 1 minute which is the interval time I set in the usual settings box. I have waited and waited even longer than 1 minute but nothing happens.

I use Windows XP and have never had this problem before.

Can you help plse? Grateful, as I am an oldage pensioner often baffled by computer navigation.
