Unable To Create PDF of Hairline Line size

I am unable to create a PDF of hairline line size from a MS Access document.   What happens is the line is not continuous, but is broken or missing.  If I made the line size wider, then my Acrobat version will create the PDF document with the lines correctly.

I am currently using Acrobat Pro version 9.2.0    I had this problem with previous version too.

Have any one used Acrobat writter to create a MS Access document with hairline line size and now have any issues ??

I would like to know what version you were using.

I would appreciate any help you can offer.

Thank You,
