Okey-dokey, I understand. And appreciate the trouble you folks went to to read and answer. (Neat, the grammar check doesn't like that double 'to' there.)
BUT -- and this is really weird -- I fixed my key trouble and you ain't gonna guess what works, even if I gave you my six decades to get it. Well, I am going too far there, aren't I?
It is just that for hours I have been poking my nose into all sorts of corners all over the Net looking at all sorts of answers and nothing was working and then I had a thought and gave it a try and it works.
I hold down the Fn key and then tap the PrtSc key three times.
First time it worked I didn't believe it, but it was right there and I saved it. So I did it again. And again. And it works. I don't have time to think about that deeply, although the idea of some sort of sticky key sort of creeps into some part of my brain, but I sense that isn't the answer why it's working.
And it creeped into my old brain that as I have an external monitor added to this laptop it may have something to do with that. Weird, isn't it? Like I have to at least tap that key twice -- once for each monitor. I just haven't had time to properly figure that answer out, but I have discovered an answer and that is rather neat.
And the print screen trouble has caused me to find this place and that might be pretty cool. And I am thinking I may just want to install the Screenshot Captor on this unit anyway. I suspect there are features available I could use.
Has anyone ever noticed any conflict with any Microsoft installed program/tool/service with the Screenshot Captor? I've noticed over the past few years that Microsoft seems to be getting nastier and nastier about 3rd-party stuff on a Windows unit, so that is why I ask. That "vote system" that causes some drives to crash is one really weird "We-Don't-Like-You" Microsoft trick, for example.
