If you are using Lynx 1.3 or 1.4, then it is very important that update to the latest version of Lynx, version 1.4.1. This update fixes a bug where a line appeared through ellipses and rectangles. This could very easily ruin your drawing. Be sure to upgrade to the latest version if you haven’t already! Version 1.4.1 is available for download on the Lynx page.
