Scroller verticale automatico

[french]

Ciao a tutti. Ho trovato questo script per delle news con scroller
verticale su dynamicdrive.com. Vorrei sapere se è possibile in
qualche modo rallentare ulteriormante la velocità di scorrimento,
che per le mie esigenze è ancora troppo elevata
(l'ho settata al minimo - 'var marqueespeed=1').

Grazie.

//Specify the marquee's width (in pixels)
var marqueewidth="200px"
//Specify the marquee's height
var marqueeheight="150px"
//Specify the marquee's marquee speed (larger is faster 1-10)
var marqueespeed=1
//Pause marquee onMousever (0=no. 1=yes)?
var pauseit=1

//Specify the marquee's content
//Keep all content on ONE line, and backslash any single quotations (ie: that\'s great):

lefttime=setInterval("scrollmarquee()",20)

Devi agire sul parametro 20 di questa istruzione.
Prova a mettere 30 o 40 o anche di piu`.

Perfetto. Grazie Mich.
