Gosh you were fast in response.
Backup...
Yes I did try to make a backup prior to downloading OSX, but it was made on an external drive WD Elements 1TB/To which I purchased with this Imac. I was never too clever at these things AND I do not quite trust a black glossy rectangle which you plug in and which does not inform any-one as to its functionings..
I would be loathe to trust it.... Save in an emergency,
Still, as they said in my old RAF Squadron, " Plod on Regardless "
Life is a constant adventure and OSX is just another which I shall have to embark upon and nobble;.....
I shall accept the sagacity of your advice and PERSEVERE..
One day, I am sure, I shall blunder upon another program which Mac will accept. One which will enable me to draw a wee frame around a written article on my screen, then print-out only that bit which I have selected...
Should you ever stumble over a simple program, as mentioned above, please give me a ding at any time..... Day or Night.
It has been a pleasure and delight working with you.
Tony
