Just downloaded the newest upgrade to Google Earth and am fairly disappointed. There's a lot I'm bothered by but the most relevant complaint to share here is the upgrade's failure to relate with the geocaching.com KML function that I ran on my old version. The old version showed geocaching placemarks with identifiable icons so that you immediately knew whether it was a traditional cache, multi-cache, puzzle cache, etc. The upgrade shows all geocaches the same with a generic thumbtack placemark. You must then visit the geocaching.com website link to determine what type of cache you are looking at.
I emailed Google Earth Help but of course they don't read individual queries. They only generate a reply based on words in your email, I presume. Regardless, nothing they sent me came close to addressing the concern I expressed.
If anyone has found a way to get this new version to interface effectively with the KML function, please let me know as it is quite possible that I just haven't figured it out yet. I'm computer smart, but I'm no computer genius.
