Edit map preset "View style XXXX" unoperational under Opera 10

Hi all,

Thanks for your fantastic module.
I've tested and abandonned it little time ago. Cause I found to many bugs and not enough features.
I must admit this new 6.x-2.x-dev (2009-Dec-12) version surprise me nicely.

I play with many features and for the moment all work well except one.

I use Opera 10 for Admin console.
With it I can perfectly edit all GMaps settings except one page.
Edit map preset "View style Earth" doesn't work. All collapsed groups can't be expanded.
First I supposed it was not editable. So I try to clone it. But problem remains.
I try with Firefox 3.5 and it works perfectly.

Other collapsed groups in other GMaps pages work.
So I suppose this problem is a very little one.

Thanks again.
Regards.
