Some Jquery/Javascript causing hover issues in safari

Question

UPDATED

I'm having issues implementing some Jquery that I'm using. At first I thought it was a cursor trail animation script I was using but now realised it's one used for a title marquee effect (I know it's not the best idea to use one but my client is set on having it)*

It seems to work fine in Chrome but in Safari it causes some hover issues on links. The cursor will flicker and not stay as a pointer when hovering any linked text or images. In safari, the pointer only seems to show on hover when moving the cursor.

Hoping someone might be able to help show me where I might be going wrong. Thanks!

CSS

a:hover {
    cursor: pointer;
}

JS

 <!-- 
 var space = " ";
 var speed = "200";
 var pos = 0;
 var msg = "PAGE TITLE PAGE TITLE PAGE TITLE ";
 function Scroll()
 {
 document.title = msg.substring(pos, msg.length) + space + msg.substring(0,pos);
 pos++;
 if (pos > msg.length) pos = 0;
 window.setTimeout("Scroll()", speed);
 }
 Scroll();
