I also rely on text boundaries. The strange lines I had to put up with in WORD 2013 was too much of a distraction to make this a workable program for word processing so I have reverted back.
This strange presentation of Text Boundaries is clearly problematic for most users. All comments are negative in all forums I've read. No positive comments.
Why is it taking Microsoft so long to correct the Text Boundaries issue in WORD 2013 when users are clearly unhappy with this feature?
