luego entre <body></body> poner lo suiente
onMouseover="clearhidemenu();highlightmenu(event,' on')" onMouseout="highlightmenu(event,'off');dynamichide (event)">
</div>
<a href="#" onMouseover="showmenu(event,linkset[0])" onMouseout="delayhidemenu()">Enlaces 1</a><br>
<a href="#" onMouseover="showmenu(event,linkset[1])" onMouseout="delayhidemenu()">Enlaces 2</a>
Hasta aqui todo bién, la duda biene ahora, por que dice lo siguiente.
Hay que añadir el siguiente evento onload dentro de la etiqueta BODY:
onload=songticker()
No se que es esto pero si no lo utilizo me funciona y si lo utilizo no, por favor, diganme el por que, i que es eso, i les afradeceria que me dijeran si lo debo utilizar o no?.
Gracias de antemano.
