Hi again Ann,
Just searched the community board and under thread "Highlighted words/phases" last July had posted this thread about the problem with words being higlighted in Bold and underlined.
Julia could not see them on the threads I mentioned and everyone else was of similar mind, so could not help me and put it down to my PC.
Like I said before the highlighting and underlining went away, could have been a few weeks or the rebooting like I said before.
Lets hope your PC returns to normal soon
Eric
