I've also seen this occur with BGL. Before I make a call to connected_components, it's fine. Afterwards, intellisense no longer works. Maybe VS has an issue with reading hpp? Just my wild guess...

My guess is that IntelliSense just doesn't work with templates - whenever I've introduced templates into my code (BOOST or not), IntelliSense becomes UnintelliSense. I also think this isn't too surprising. Considering the potential complexity of templated code, expecting IntelliSense to handle it well is probably not reasonable - IntelliSense would have to *execute* the entire template metaprogramming subset of C++ "on the fly" to handle template types completely. - James Jones Administrative Data Mgmt.
