Hey everyone,
During a meetup with some of the Ushahidi Devs last night, we discovered that clustering works on Unix-based platforms and not on Windows platforms. The source of this problem lies in the platforms caching mechanism; thanks to Firebug!

Whenever an Ushahidi instance is accessed, the map data is cached to disk under application/cache and the cache files take the following signature:
 page_json?c=0&s=1259614800&e=1262293199&m=0~~1280310643  

The above is a valid file name on Unix-like platforms but not on Windows because the latter does not allow file names to contain the characters ? : *  \ /  < > " You'll notice that the sample cache file above contains "?".
