It's a bit lengthy, but here goes...
There's a button on the keyboard prt sc which grabs an image of your screen.
That can be pasted into an e-mail or other document; but it will still not be available for posting on the web.
I paste the image into my Photoshop® wannabe PaintShopPro and clean it up to my satisfaction.
I then post it to a photosaving website. I use Photobucket.
Once it's there, I can post it to FR, since it now will have a unique URL address.
I thank you! When it comes around next October in the sky I will attempt it!
