        So - if the systray is running - then we have a ton of LibreOffice
already there in the background; UNO is bootstrapped and the configmgr
startup is done; apparently though we don't have the sw and sc DLLs
loaded - I guess we're in some empty-shell / sfx2 style mode.

        Right; so - we could easily do a couple of UNO service activations
there to suck in writer and calc I guess.

        A patch like that would have a good chance of getting merged I
think :-) Of course, configuring which ones you really want to load is
more of an interesting problem, but I guess impress is faster and
smaller to link than writer+calc.

        Then again, clearly the quick-starter can become a slow-starter if it's
all loaded in, and then very slowly swapped out to disk again through
lack of use :-)

        Thanks for picking it up Caolan !

        Regards,

                Michael.
