eCopy Highlight Markups Export to PDF as Opaque Squares

[ProphetX]

When working in eCopy Desktop 7.1, you can use the Markup tool to add highlighting to text. We are experiencing an issue when we export this highlighted eCopy document to PDF. When it opens in Adobe Reader, the transparent blocks of color created by the highlighter in eCopy have become clear boxes with thick (8pts?) opaque borders of the same highlight color. We use Windows 2000, eCopy 7.1, and Adobe Reader 5.0 and occasionally 6.0. This happens whichever version of Adobe we use.

Is there a way to create the PDF document with the same highlighting as in the eCopy document?
