In rare cases, selecting text across multiple cells of a nested table can cause Netscape to go into an infinite loop. The export version of Netscape 1.12 supports only the RC4-40 cipher. Using this version to connect to servers that support other ciphers should give you an error message saying that the cipher types don't match. Time stamps on mail and newly created bookmarks may be in GMT, not local time. A link that you open in a new window through the popup menu is not drawn as visited in the old window.
Printing sometimes makes forms controls appear in weird places in the window.
Printing will sometimes cause the contents of a window to become invisible. The popup menu, when used over a broken or delayed image icon, sometimes contains enabled items that should not be enabled. Delayed images with alt tags sometimes draw a little too far to the right and touch the text following them. Switching document encodings in preferences while a document is still loading can cause a crash. If more than one file is dragged onto Netscape, only the first file will open.
