This was one of those usability problems that was subtle enough that I never made the effort to fix it. Well I was using Google docs to take notes and it just got on my nerves. How could the smart people at Google be short sighted enough to make the highlight color the same color as the background of the page (which totally defeats the purpose of highlighting). I googled it and found this article which let me know others were having the same problem.
Apparently, it is an issue just on Windows. But if you are having the problem and want the solution. It’s simple.
In the google docs menu:
[cc]File > Page Setup
Change the Page color to a slightly darker white color.
Highlight until your heart’s content.
