I travel a lot and I use Google Maps to help me get around. The My location feature is very handy when you're lost and find a Wi-Fi hotspot but it has one problem.
My Location likes to cache the previously used location somehow. When you move to a new location it often still shows the previous location. If I click on the little My Location circle above the little Street View person, it does not update. Clicking on Reload does not update it. Forcing a cache refresh with CTRL + F5 does not update it. Google Maps help page on the feature offers no hint or clue.
The only thing I've found that works is to use a different browser. My OS is Window 7, my usual browser is the current version of Google Chrome, 14.0.835.202 m and my backup browser is the current version of Opera.
But this is an ugly workaround since I'm using a netbook I'm often low on memory or battery and starting a whole second browser users up more of both than just getting Google Maps to realize I've a moved a thousand kilometres should!

One way is to click the little circle above the Street View man's head. This forces it to detect your location, and Maps will ask you for permission to share your location. Assuming you accept, or have turned on auto-accept, it should then update your position to your new location.
The only time it seems to fail is when you're on a network that Google Maps can't recognize. But that seems fairly rare.
