I have found a bug in Map Compare and probably a host of other maps as well, in that if two caches have identical coordinates, while both show on the map (except that you can't tell as the cache icon perfectly overlaps, but I could tell as one has a found smiley in the corner masked by the cache icon above it), when clicking on the icon we get a popup identifying only one of the caches and cannot click on the other. Perhaps add a "next" link so we can pick up the details of the other? Or multiple clicks on one cache icon cycles through caches at that coordinate? (and while about it, make it fuzzy - cycles through cache icons that overlap).
Caches can have identical coordinates if they are different types, eg multi and traditional, or if one is archived.
For an example look at GC57WBM and GC57WBV, see image at
