The Speed Grader highlight and strikethrough tools are causing me much frustration. I am having to click and drag five to ten times every time I try to highlight a word, sentence, or phrase on which I want to comment. The tool simply won't start marking. I know I'm not describing this well, but this is all I have. Possibly related, when I do manage to get it to work, the marks aren't clean; they highlight or strikethrough part of the previous or next word. I have not used Speed Grader in about three years. I did not experience these issues before.

I am trying to mark essays submitted as Word documents. The problem is the same on the four different computers I have tried. Any help would be greatly appreciated. I'm not sure how I am going to make it through the term at this rate since I am wasting so much time trying to get the tools to work.
