How much inactive time can elapse for a client using the interactive designer. Before it would close out and not save edits?

 Good question, we do not have any activity timers on forms based eDoc or the Interactive Designer. 

I have seen template range from 1 field and 1 page to, close to 200 fields and multiple pages. So trying to determine the right amount of time a person "should" spend on every template would be impossible.
