Cross browser between IE5 and IE6 Arrgh!!!

[Booshed]

I've got a weird fault that happens on IE6 but not IE5 when trying to open an href link (to code used to open Excel spreadsheets). Basically the code where the error is raised (after clicking on link) is as follows:-

<a href ='/test/testing/testFile.asp?fileID=51511&ud=28362&fileno=4'>Ready</a>

The error (Description: Unspecified Error , Err no: -2147467259) that comes up is actually referring to the line highlighted below. Do you know why this would be the case? displayHelp does exist as a div tag.

function hideTips() {
var oDisplay = document.all['displayHelp'];
oDisplay.className = 'helpHide';
}

hideTips() is called by the code below which is loaded on a onload event.

function setBodyEvents() {
var oBodyTag = document.all['IDBodyTag'];
oBodyTag.onmouseover = new Function("showTips()");
oBodyTag.onmouseout = new Function("hideTips()");
oBodyTag.onclick = new Function("showActualTips()");
}

Any ideas as to what could be triggering this error or the solution to it would be greatly appreciated.

Cheers
