I'm having a problem on 64-bit windows (no other platform, 32 or 64-bit), where only the first slot in a signal is being called. No exception is being thrown, which is usually how this kind of thing happens. Is there any way for me to walk the list of connected slots right before I invoke the signal? It would be helpful if I knew if somehow the slot had become disconnected, or if boost::signal just wasn't invoking for some other reason. -- Nick
