Tentative solution to Marauder's Map problem

Hi,

While reading PoA, I remebered that there were quite a lot of 
questions regarding why such and such person was not viewed on the 
map (why didn't Lupin see the second Harry and Hermione, why didn't 
Fred and George and then Harry see Peter Pettigrew? etc.). 
Well, I had what seemed to me like a brilliant idea, but I haven't 
checked it against all possible evidence: I think that the map only 
shows people/creatures that are moving. I thought of that when Harry 
looked at the map for the first time - it showed Dumbledore *pacing* 
in his room, Mrs. Norris walking somewhere, etc. 
If this is true, then the map didn't show the second Harry and 
Hermione because they were sitting under the trees, they weren't 
moving about. Also Pettigrew - it's quite reasonble to suppose that 
all the times the map was used, he wasn't moving (Ron did say all he 
did was sleep and eat, right?). 

Comments?
