CF Report Builder field not stretching with overflow

I am using CF Report Builder build 144677 on CF 7.0.2 and have a large SQL Server text field that needs to stretch. If I stretch the layout height for the field to a larger value it works, but then of course I get a bunch of whitespace if the field value is smaller. I have tried a variety of property settings and moved the field into the report header, detail and footer sections, but have been unsuccessful. Assumed that "Stretch with Overflow" formatting property set to True should have done it, but it does not. I modified the Layout and Processing properties as well including setting position type to Float and Fixed, but to no avail. I also tried various conversions on the field type itself to see if that mattered, again no help. As a side note, I am able to get subreports to stretch. Suggestions would be appreciated.

Also noted there is not much help with the Help system. Embedded help does nothing.
