Invalid Argument in function moveMouse

[Globox]

Hello to everyone here. My first post

I added TRY/CATCH to all of the boxover functions in order to track down a problem. So first off, if anyone wants I can post the source to save you doing the same.

I added boxover to some links in one of my asp pages to try it out and have to say that on the first time of rendering the page, the tooltips work a treat. Clicking the link causes the existing page to be saved into an array (to avoid unnecessary Oracle access) and details for the new page are shown along with a 'Back' button.

When I click the 'Back' button, the previously stored page is re-shown but now when I hover the cursor over the links, I get 'moveMouse - Invalid Argument'

Here is my save page function

function save_current_page()
{
var func = "save_current_page"
try
{
pagenum += 1
stored_pages[pagenum] = document.getElementById("fullpage").innerHTML
}
catch(err)
{
alert(func + " - " + err.description)
}
}

and the code to show the previously stored page

function btn_back()
{
var func = "btn_back"
try
{
document.getElementById("fullpage").innerHTML = stored_pages[pagenum]
pagenum -= 1
}
catch(err)
{
alert(func + " - " + err.description)
}
}

The stored_pages is a previously defined array and the funcs work fine. Just wondered what could be causing the error in moveMouse.

Anyone else had similar problems?

Thanks
