As mentioned in my previous post, you can replace the standard list item forms with InfoPath browser based forms (SharePoint 2010 Server Enterprise only). This is a great feature but there are some gotchas that can be hard to find answers to; mostly because these types of forms have different limitations and options than other InfoPath forms.
I was using this feature and had a form view for New, Edit & Display and everything was mostly working. However, my display view was annoying the crap out of me. My list has a couple of Multiple lines of text columns that allow Enhanced rich text (Rich text with pictures, tables, and hyperlinks).

Turns out I had set the view to Read-only (This is the Display view so that seemed like an important step to me). In my desperation I opened up the View Properties and unchecked the Read-only box, hit OK and re-published the form.
When I opened the List Item Display view everything looked perfect. Apparently InfoPath and/or SharePoint is smart enough to know to make everything uneditable when displaying a list item:
