Now in our live environment a second usability question was raised in regards to the dialog boxes the web interface shows in cerstain situations. This time it's the point a user tries to close the TM1 tab in the Internet Explorer (8 or 9).
Usually the following popup box appears:

In general no problem. As some of our users have access to our system through a Cisco firewall webinterface it seems that you have to click "Leave this page" a thousand times until the tab is closed

As we've no possibility to adjust the firewall webinterface I'm now searching for a possibility to deactivate this popup box and closing the tab without further notification. Is there any parameter in the web.config / tm1s.config or any other config file?
Thanks again for your support,
best regards
Thorsten
