195658 - Scrolling text in Status Bar flickers, over-writes

Status: VERIFIED DUPLICATE of bug 104532

(Core :: JavaScript Engine, defect)

Description

[David A. Cobb]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.4a) Gecko/20030228

The page uses the following JavaScript to create a scrolling marquee effect in
the status bar.  What actually happens is two messages chasing each other across
the bar, flickering so badly they're illegible.

Quite possible it's the script that's faulty - I'm no expert.

<script LANGUAGE="javascript">
<!--
	var scrlStr="Most Holy Mother of God, save us"
	var width=150;
	var strLen=scrlStr.length;
	var pos=1-width
	function scroll()
		{
		var scroll = "";
		pos++;
		if (pos == strLen) pos =1 - width;
		if (pos<0)
		{
		for (var i=1; i<=Math.abs(pos); i++) scroll=scroll+" ";
		scroll=scroll+scrlStr.substring(0,width-i+1);
		}
		else
		scroll=scroll+scrlStr.substring(pos,pos+width);
		window.status=scroll;
		setTimeout("scroll()", 60);
		}
//-->
</SCRIPT>


Reproducible: Always

Does it happens when you have only with one tab or after opening several tabs?
(the latter one is bug 104532)

Bingo!  Thanks, that one missed my search.
Particularly note the comment regarding the mess with a couple of tabs all
trying to drive the Status Bar.
