Hi Mike,

you should have a look at TextMaker, the word processor from SoftMaker Office. It has all the markup options and commenting features you need, and is seamlessly compatible to Microsoft Word formats of all kind. I don’t have any problem going back and forth. Interface is similar/familiar to that of MS Office 2003 (no ribbons), so there’s not too much of a learning curve. Coding is tight, and program is small and runs fast. Price is very reasonable (SoftMaker Office costs $69 for including three Licenses).
