lib_bwcheck.prototype.toString = bwToString;

function lib_bwcheck(){
this.ver=navigator.appVersion
this.agent=navigator.userAgent
this.dom=document.getElementById?1:0
this.opera5=this.agent.indexOf("Opera 5&quot

>-1
this.ie5=(this.ver.indexOf("MSIE 5&quot

you are doing this :

document.write(document.write(string))

so indeed what you want to do is have this :

function bwToString()
{
return "<table border='1'>"
+ "<tr><th>Description</th><th>Property</th><th>Value</th></tr>"
+ "<tr><td>Version</td><td><i>ver</i></td><td>" +this.ver+ "</td></tr>"
+ "<tr><td>Useragent</td><td><i>agent</i></td><td>" +this.agent+ "</td></tr>"
+ "<tr><td>Dom</td><td><i>dom</i></td><td>" +this.dom+ "</td></tr>"
+ "<tr><td>Opera5</td><td><i>opera5</i></td><td>" +this.opera5+ "</td></tr>"
+ "<tr><td>IE6</td><td><i>ie6</i></td><td>" +this.ie6+ "</td></tr>"
+ "<tr><td>IE5</td><td><i>ie5</i></td><td>" +this.ie5+ "</td></tr>"
+ "<tr><td>IE4</td><td><i>ie4</i></td><td>" +this.ie4+ "</td></tr>"
+ "<tr><td>IE</td><td><i>ie</i></td><td>" +this.ie+ "</td></tr>"
+ "<tr><td>mac</td><td><i>mac</i></td><td>" +this.mac+ "</td></tr>"
+ "<tr><td>NS6</td><td><i>ns6</i></td><td>" +this.ns6+ "</td></tr>"
+ "<tr><td>NS4</td><td><i>ns4</i></td><td>" +this.ns4+ "</td></tr>"
+ "<tr><td>Ondersteund</td><td><i>bw</i></td><td>" +this.bw+ "</td></tr>"
+ "</table>";
}

so that you actually do : document.write(string)

Hope this helps. Gary
