Operation times out after export to CSV in Chrome

Hi all,

I download no problem data from a ListGrid to a CSV file, both in Firefox and Chrome.
But while in Firefox the application works immediately after the download, it gets stuck in Chrome for a minute until it times out with the message "Operation Timed Out."

Thanks in advance.
Vittorio
