The previous version of Basecamp worked fine. "Laborious" in a previous post is the correct word. I keep centering on the area of the map I want to find an address and it takes me over 500 miles from where I'm searching. I tried to enter the zip code but it keeps being erased leaving only the street address. Over 30 minutes now trying to locate one address and I just have to give up. It doesn't work. What a total mess! I'd stay with the previous version if you haven't already updates to 4.1.
Zip/Postcode seraches aren't yet in BC, later we're told!
Other than that address searches seem to work for me, are you sure you have the correct address and entering it correctly? Apparently it should be 'street name, city'
