That sounds rather hazardous to me.  To lose all of one's data instead

of saving it, after a potentially long session's work, because of a

check box incorrectly checked when starting the session, surely

wouldn't please many users?

I think I must have misunderstood the use of D-BUS here, then.  I had

thought that LADI was a D-BUS service which the application connected

to, so that LADI would know whether an application was running in a

"LADI-aware" state or not.
