Geo Mashup problem

I’m having some problems with the geo-mashup plugin. Links from posts don’t center very they are supposed to. The connected flag or coordinates should be the place to show, instead it shows the default view.

If I send the zoom parameter in the url, that works but not the latitude or the longitude.

I’m using Geo Mashup version 1.0.3
