Just a quick note that the work-around for Word’s mis-rendering (rending?) of HTML is a satisfactory, if short-term, help for my client. The work-around is to open the the email, then select “Other actions…View in browser.”
It also looks like biggest problem isn’t with the TextBoxes so much as with the div and span elements I used instead of a (HTML) table. Which chaps my butt a bit since the page would have been so much easier to create and maintain using tables, but I had succumbed to peer pressure that “tables are bad.” Anyway, will rework with tables and then reasses how bad the input elements appear.
