Long/Lat not being created when apartment number is included in "Street" field

I discovered that if I include an apartment number on my address, I won't receive the geolocation information from Google. I am concerned that the casual users/editors on my site will enter their apartment number in the Street field as I did since it isn't a strict convention to enter apartment/suite/floor/etc information in an "Additional" field - in fact it's the first time I've seen such a reference - it's usually "Address 2" or a field for Apt/Suite/Floor, etc.

I suggest that there be some more helper text associated with the Street and Additional fields to warn people to ONLY enter street information in the Street field and any apartment/suite/floor info in the Additional field.

And/or, if a lat/long comes back from GMAP as 0.0000... then strip off anything after a comma and try again?

THANKS FOR THIS MODULE ---- IT'S GREAT!
