[ROOT] test/Event example

Hi,

I examined the Event demo in the test directory and found something
which I do not understand. I run ./Event to produce Event.root, then
T->Draw() to obtain tree variables. The results on the number of
tracks are different for T->Draw("fNtrack") and
T->Draw("GetEntries()") (fTracks.GetEntries()). The first one is
populated around 600 while the second one is typically 360.
When events are written on file both numbers are equal.
What's wrong? Is it a bug? 
cheers
