Why doesn't Google Latitude automatically update my location?

[saqib]

I have added the Google Latitude gadget to my blog at

. However it doesn't automatically update my location. I have bring up Maps on gPhone every time to get the location to update.

How can I set it such that I don't have to bring up the Maps for my location to get updated? Any thoughts?

Thanks
