I have a strange problem. On my developer machine, when I view QVW's with Google Maps, all my maps come up with the data offset. This offset changes with the map zoom level. See below. Obviously all the blue dots are 'shifted" to the "southeast".
When I open the very same application on our server it works fine.
The QV version on my machine and the server are the same and the Windows screen resolution is the same.
Changing the DPI setting did fix my specific problem. You may be having a different problem. I would suggest creating a new post and attaching a specific example of what you are seeing and what Google map settings you have.
