[OpenLayers-Users] google overviewmap southeast shift problem

Fri Feb 5 06:44:22 EST 2010

Hello List,

I think i have found a bug in the OverviewMap Control.
I have a map with an GoogleLayer and an overviewmap which also should
display an Google Layer.
When i open the overview Control the center in the overwiew is not on the
correct position. It is shifted in southeast direction depending on the
zoomlevel.
I wrote a little test case and found out that when i call the
maximizeControl function before i set the center of the map the center on
the overviewmap is on the correct Position.
I will keep on investigating this problem, but if this is an known bug and
there is an solution for this problem i would be happy to hear it!!!

cheers 
Max
