Sorry to nag, but have noticed some top-posting here lately. Also some don't trim posts they are replying to when it would be possible. A few years ago I suggested trimming trailing white space from the source files. I don't know if anyone has done so, but I still recommend it. Boost is often cumbersome. Trimming this trailing stuff would be a step in the right direction. grep " $" * -- Brian Ebenezer Enterprises - In G-d we trust. http://webEbenezer.net
