Timothy-

I checked over your code and it seems to be working just fine for me.  I did
do some indentation clean-up for you (smirk) but aside from that, I just
took out the addition operands (++) from your txtStr[i++] references and
threw the rand code in there.

You may want to code something to keep track of the last number generated,
and then check that number to make sure you don't re-generate 2 "random"
numbers in a row (it currently does that quite a bit, looks like it's
pausing randomly).

Take a look (mind the wrap):

<!--
var Speed = 500;
var txtStr = new Array("1","2","3","4","5","6","7");
var i = 0;

if (document.layers) {
	document.write('<ilayer id="NN4"><layer id="NN4" height=25
width=100%><\/layer><\/ilayer>')
	var temp =
'document.NN4.document.NN42.document.write(txtStr[i]);'+'document.NN4.docume
nt.NN42.document.close()';
}
else if (document.getElementById) {
	document.write('<div id="message" style="position:relative;">...<\/div>');
	var temp = 'document.getElementById("message").firstChild.nodeValue =
txtStr[i];';
}
else if (document.all) {
	document.write('<div id="message" style="position:relative;">...<\/div>');
	var temp = 'message.innerHTML = txtStr[i];';
}

function rotateR() {
	i = Math.floor(Math.random()*txtStr.length)
	eval(temp);
	// removed the following...
	//if (i == txtStr.length) i = 0;
	setTimeout("rotateR()", Speed);
}

window.onload = rotateR;
