[ZendTo] Re: FW: Issue with Chrome browser - "Leave this Page"

[Jules]

I've got a quick fix for this. Unfortunately it means you can navigate 
away from (and hence abort) a running upload, but it stops the Chrome 
warning, so is better than nothing.

You want to edit /opt/zendto/templates/new_dropoff.tpl

Find the start of the "submitform" function, and add the last line of 
this little code snippet:

<script type="text/javascript">
function submitform() {
   if (validateForm()) {
*window.onbeforeunload=function(){}**
*
