PWS square wave and RC

It seems I have some basic issues to understand simulation.

The circuit should explain a square wave and RC reaction, the signal source should make two pulses 1 ms each.

1) The PWS() will add the point 0,0 if the user doesn’t - OK. But it doesn’t start at 0,0 ?

2) No warning on double definition of PWS value at time zero? The (not) reaction of solver remains unclear to me.

3) I do not understand the transient plot of both, Cap1 and R2 in my example. How come a capacitor already starts loaded?

Could please someone explain that to a newbie?

Is it a bug or a feature?
