Troubleshooting: cursor won't highlight when I click and scroll

[delusions]

I have an unusual problem that I imagine is because I'm using an old laptop (Windows 8.1)

When I click on a body of text and scroll for the purpose of copy/paste, changing the font, etc.; the text doesn't highlight. Interestingly enough, those features are still functional, but it won't highlight so I can see the text before I use those features.

Can anyone tell me what I should do to fix this problem? Thanks!

I'm not quite sure what you're doing exactly. When I want to select text, I set the cursor at the beginning of the intended text block, press the mouse button, keep it pressed and draw the mouse to the end of the text block. When I click into the text and scroll, nothing happens, but that's normal behaviour.
