She came and told me straight away and said it appeared on her screen. She pressed loads of buttons and it went away. I said I would sort it out for her.
I've just checked her computer history of sites visited and worked out she must have been back for another look. There were security controls and I am not sure how it happened, but have been up there for hours re-setting all the parental controls. I have to accept responsiblity for them having not been strong enough to start with.
But where from here? I will want to talk to her tomorrow about what has happened but am not sure what line to take.
Has anyone had a similar experience who would be able to give me advice?
