Pretty sure I remember there is an issue with GMaps and this.  There is an issue in the queue and last update I noticed at least part of the solution was available as a patch.

Subject: [support] D6 GMaps Problem

I had a GMap that was working fine, but the customer wanted some attachments. Now the data points cannot be clicked to go to the node. What did I mess up?

May the peace of God be with you.
