Google Map and Internet Explorer

Hey.

In first hand, this module looked just like what I needed, but som major issues did that I'm not that sure anymore, so please help me figure them out.

Is is possible to make the map view Google Map instead of Yahoo Map?

I have som trouble when searching for an address in IE. When I push the search-button it just reloads the page and when the page reloads, the map is gone. Happends in both IE 7 and IE 8.

Attached is an image of how it looks in IE when I have searched for an address.
