The problem is related to the display of 'Order Description' field, with a very long description. In edit mode the field displays correctly with the data wrapped. However in view mode, the data is not wrapped. The Read only view of the change description is not doing a word wrap on the web page and it is making the change information so long that you have the scroll from left to right the whole time on the page.
It appears that the dtlTextbox macro by design does not have an 'align' or 'justify' or 'word wrapping' property. To this end we require an enhancement to this macro.
