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

[Jules]

We're still working on a better fix for this. Re-enabling the 
unload-handler immediately after the upload has started doesn't appear 
to work, when I'm sure it should. Don't worry, work is continuing on 
this one, I'll post a new version once I have a better solution.
