Questionnaire Scroll Bar

The Question Text Column scroll bar in my Certification Questionnaire is not working.

I have a long question text which does not fit the default cell size. The scroll bar is not clickable/draggable, so my reviewers aren't able to view the entire question during certification.

The workaround I have is just to expand the column size so that the text fits into the cell. I am wondering if anyone has the same user experience or has a solution to get it to work? My current software version is 7.1.3.
