I added a setCenter() cal and it works fine now;

Interesting problem.
I came up with the following solution :
I write 2 seperate event handlers which each check if the other
distance has been calculated.
If it has; a third function is called to fill the appropriate div with
the appropriate data
here's the code:
function onGDirections1Load()
{
dist1 = this.getDistance().meters;
if(typeof(dist2) != 'undefined')
{
display_distance(dist1+dist2);
}
}
function onGDirections2Load()
{
dist2 = this.getDistance().meters;
if(typeof(dist1) != 'undefined')
{
display_distance(dist1+dist2);
}
}
function display_distance(d)
{
document.getElementById("gdirections").innerHTML = "Distance: " +
d/1000 + " km ";
if(trip_kind == "dropoff")
{
document.getElementById("gdirections").innerHTML+="(" +
dist1/1000 + " + " + dist2/1000 + ")";
}
document.getElementById("distance").value = d;
}
Any comments or improvements?
