I find the highlighted bar under the cursor confusing and problematic (for me, at least). Is there some way to remove the highlight bar under the cursor so that only the selected folder or file is highlighted?
Yes, turn off Preferences / Display / Options / Use visual style to draw items (overrides selection colors).
You may then also want to adjust the colors of things under Preferences / Display / Colors and Fonts, as the defaults are designed around that option being on.
Thanks. That's just what I needed.
