I will try to explain this clearly. I have Windows Vista if that makes any difference.
Basically if I want to shut down/log off/sleep the computer I press the little windows icon bottom left of the screen. It then comes up with various options so I can switch off etc. When I press on one of them, nothing at all happens.
I suspect dd1 has inadvertently pressed something to cause this.
Any advice please (I am not technically minded at all btw)
Thanks
