Hello everyone

I'm moving from Word 2003 to Word 2016 for tracked-changes jobs. In Word 2003, it's easy to see separate comments because all comments have a little border around them. In Word 2016 (possibly for esthetic reasons?) there are no borders around comments. I only see a border if I hover with the mouse over the comment. This makes it difficult to distinguish between comments if there are many of them. Is there a way to customise the comments so that they always show a border?

Thanks
Samuel
