Creator timeout

I asked this a while back have had no reply. Come on folks, it can't be that hard!

I just need to know how long it is before Zoho Creator logs you out or drops the connection, if you load a form and then wanter away for a cup of coffee. Is it half an hour? Ten minutes?

More importantly, can this setting be tweaked anywhere? I have some people that need to run training courses, and the last thing we want is for the system to time-out before the clients click Okay!
