It's only a guess, but based on your 'cure' being effective ... When GGeoXml is used to display KML, it gets parsed at Google' servers. Google accesses your KML directly, your KML gets cached at Google. So, if perhaps your server is bit busy sometimes or slow to respond, Google might get a truncated or broken copy of your KML in its cache, which of course won't display. How long the cache lasts is not clear, some hours at least. Changing the filename would immediately get round the cache. If that is whats happening, what to do about it is trickier. You might use one of the client-side KML parsers (GeoXml,EGeoXml), thus avoiding Google's cache altogether. This would mean yet another script to load and process on your webpage, but as it is a small/ simple KML that might be acceptable. Or, a simpler way, you might add a cache-busting random number to your GGeoXml URL request to circumvent the cache. You'd lose the speed benefit of the cache too, but again this may be acceptable. -- You received this message because you are subscribed to the Google Groups "Google Maps API" group.
