Of course, as soon as I send this email, it *STOPS* working.  I cannot 
figure this out - it successfully went into suspend, and now I can't get 
it to go into it.  I haven't recompiled anything, haven't changed any 
settings, nothing.

I'm so lost.. Does anyone have any hints, clues, etc?  I have a spare 
D610 now to experiment on - I'm open to suggestions..

Eric
