pain in the butt

Any time I click on anything on my new Widows 10 computer, a box shows up that gives me every option besides the one I want--just keep doing what I'm trying to do. It is so frustrating I'm almost ready to try to put together my old computer so I can blog without all the interruptions. And when I hit backspace to erase something, the cursor jumps back to the beginning of the typing.

Maddening is what it is and and I have no idea how to fix it. (for example, I just hit 'x' in 'fix' one more time than I meant to and it took me a minute or so to 'fix' fix. How crazy is that?) And I wanted to add the ) and had to work to do that.

When your computer is smarter than you are, you're in trouble.

And it's a pain in the butt.

Just to let you know, I realized I'd written 'it' a pain' rather than 'it's a pain' and it took me about a minute and a half because boxes kept popping up when all I wanted to do was write a 's'.

How stupid is that--or how stupid am I? Same result.
