Mozilla is, however, harder to trick into allowing the layer overlay to obstruct links below it. If the domain from which the image is sourced does resolve but does not contain the image file, Mozilla reduces the image to a link with the ALT text. If the domain doesn't resolve, it will use a placeholder image in its place. IE5 and Mozilla do not support disabling CSS in an easy manner. A layer can be thought of as a separate document that resides on top of the main one, all existing within one window.
Text links appear to be unaffected by the floating image while most image links are affected.
Additionally, there might be unusual boundary conditions involved in the way the floating image is handled. Resizing the Netscape window or changing focus causes different things to link to the exploit page and alters cursor display behavior when hovering over things. Additionally, bringing in the cursor from the top generally results in the hand cursor, while bringing it in from the status bar results in a pointer cursor, although in both cases object clickability is identical. Everything in the message frame links to the exploit page including the drop-down list containing folder names except for about 20 pixels at the top of the message frame where the outline for the broken image is visible. Only if the server from which the image originates does not resolve.
