hi Jim
thx for the reply, as i repeat it here to reply back item by item:
One thing I can think of that may cause a problem. (may as in I'm guessing here):
1. Camera set to use grip battery first
checked that out already: it was on Automatic (default factory setting) and i tried to re-assign the Lithium batteries (in the grip) as the first ones to be used by the camera, which did not change the situation.
i have also tried turning the grip on first and then the camera, but no difference. in fact, according to the grip's instruction manual, the camera can still operate with the grip set to the off position, which is true according to my own experience too. (the grip has to be turned on specifically only when it is to be used, say in its intended vertical position.)
2. Battery in camera
do you mean if it is faulty?
if so, then i'd have to say that it's quite new and as i mentioned, the camera works fine without the battery grip installed, using the in-camera battery alone. then if i remove the in-camera battery and use the power grip alone, i still get the same problem: the camera has to be turned on, turned off, and turned back on again, which it turns on rather quickly then, after only 1" or less instead of 5".
the problems then lies somewhere in or around the power grip thing, say in the contacts for example, as Bert has mentionied it in another reply here too. but i'm really not sure though ...
3. No battery in grip
there is battery in there: six Advanced Lithium ones by Energizer ("Spock, Energize!" ;-])

couldn't agree more! kind of the same attitude here, albeit not everybody is happy with me 'behaving' that way!
