[Chameleon] map image not placed correctly

[bartvde@xs4all.nl]

Hi list,

does anybody know what is causing the map image to be displaced the first
time a Chameleon page is loaded?

The border is placed correctly, but the map image is mostly around 50
pixels down from the border and a bit to the right.

After a zoom action, this corrects itself.

Any quick and dirty solution for this?

Best regards,
Bart
