At the mentionned above, dotted lines appears across multiple columns of the table. A screenshot of the anomaly is available at http://pages.infinit.net/blanalex/mozilla_render.png
Looks like a problem with the BACKGROUND option in <TABLE> tags. Reassign to HTML Tables. Confirmed on Linux build 2000.02.17.15.
Works fine on Windows NT build 2000021708. Adding pp keyword.
