Comprehensive Google Map Plugin question

First, I want to say I am really impressed with the Comprehensive Google Map Plugin! I think it’s an impressive piece of work — and very useful — but I have a question about a small problem I’m having.

Everything seems to work well when I use my cell phone to view pages with Comprehensive Google Map Plugin maps on them, but when I’m on my PC and I open the posts/pages, the Comprehensive Google Map Plugin maps load and then go grey with the error:

There was an error creating Geolocation marker: Position acquisition timed out
Proceeding with normal map generation..

This happens over and over again, about every four seconds, requiring you to endlessly dismiss the error screens, which is a hassle.

I’ve tried different ways of setting the location for the map (coordinates, address, KML file), but I always get this error when I’m on my PC. Is this because my PC doesn’t have a GPS? Should I worry about it? Thanks for your help…
