I display some pins on a map:

but when I move the map and zoom out, the pins also move:

any idea about the problem?

I've found that this problem is related to my div' style:

<div style="overflow: hidden; width: 100%; height: 100%;" id="myMap"></div>

-> doesn't work

<div style="overflow: hidden; width: 400px; height: 300px;" id="myMap"></div>
-> works fine

How could I display the map in "full screen" (my map is hosted in a Winform usercontrol, when the user resizes the form I want the map to grow or shrink)
