I'm back. Sort of....
It was a pop up thingy that caused the problem, and I did all sort of things to try and fix it - enabling and disabling pop up blockers, etc. but nothing worked. Back to the expert next week.
The other thing I can't do now is click on the blog links on my side bar. Well, I can click on them, and keep clicking for 10 minutes, but nothing happens. The blog page I want won't open. So I can't visit any of my blog friends unless they leave a comment here and I click on their name, which will then take me to their blog. Most of the time.
And Microsoft Office has disappeared from the computer which means I can't type any documents. R said I wouldn't be able to type on my blogs, or emails or anything, but I haven't had any problem doing either of those things.
Oh well, R didn't charge me anything for fixing it, and it took him about four hours. All I could offer him was an invitation to stay to tea, as it was after 6 pm by then, and as he is a single lad, he was happy to stay on for a meal. All these art and craft course I do are really no help with the practical side of life in the 21st century. Perhaps I should book myself in for a computer course instead.
