Problem with exporting to a PDF

I am using wptools version 4 and version 1 of wpdf in Delphi 7.

if in the wptools I turn on a line like :

theReport.currAttr.LineVisible[brdTop] := true;

when i then export to the pdf, the lines do not show up.

Is this a known problem with the older version? Has this been addressed in a new version? Is there a fix for the version I have?

Any help is greatly appreciated.

Thanks for the answer.

One more question. Can the wPDF be upgraded independantly of the wptools? Will wPDF 3 work with wptools 4, or do I also need to move to wpTools 5?
