>Working with an existing reports, I would like to change the top/side rulers and dimensions unit of measure. When I open an old .frx, the rulers shows in inches, I want to switch it to centimeters for better precision. (When I create a new report, the dimensions are in centimenters but old existing reports are in inches)
