<div id="map"
style="width: 100%; height: 100%; background: lightyellow;">
</div>
</body>
</html>
The fact is that when I maximize the IE7 browser windows and change the base
layer, the new map automatically moves his center (x,y) downward and toward
the right as it was panned in that direction.
It seems that all the maps must be reloaded.

Leonel

Please provide a test case where this happens. It is hard to help you out
with so little information. Cheers. Eric
