When I click on "Geocaching.com Map" at the bottom of a cache's description, the map loads but no icons show for any caches including the one I've come from. I've tried leaving it for a while to see if the images were loading slowly, but they didn't appear at all. I can zoom out and, unless every single cache has been muggled and disabled , the map doesn't show any. However, if I move my mouse pointer about, I may get a cache name pop-up when I get to where an icon should be.
I'm using Google Chrome 18 on Win XP. Although it's also the same when I try IE7 and Vista.
