            Description

            The file in question (confidential) had a few check boxes which where not being drawn. After a few falls starts related to AcroForms I managed to narrow down the block of operands causing the problem.

              When plotting out the m and l postscript a box is drawn followed by the cross but the screen representation was not so. A little closer look at the content parser and the B and b operands where stroking then filling aposed to filling then stroking as the spec states.

              Surprised this issue didn't come up in the past but the B tokens aren't used very often by generators.

              Closing issue. Will open again if any regression appear out of test results.
