Do I have my beersmith configured incorrectly? Obviously a longer boil will yeild a higher gravity. When I change my boil time, the estimated OG stays the same. For some reason I thought it took boil time into account? Anyone?

Why would boiling longer create a higher OG? The amount of the sugars don't change.

The only way a longer boil would change anything is if you boil off more liquid in a longer boil. So, if you went from 7 gallons to 5 gallons in a boil usually, but in the next batch you went to 4.5 gallons, you'd have the same amount of sugars in there but less volume.

I was under the impression that the water would boil off and leave more sugar behind leaving you with a higher gravity due to less water.

Beersmith only looks at your batch size for OG calcs. If you increase the boil time, it doesn't decrease the batch size, it increases the pre-boil volume.

Your right a longer boil would mean more boil off, and therefore would mean a higher OG. Yes the sugars would be the same but the water would be less which = higher OG. But like NCbeernut said beersmith increases your pre boil volume to account for a longer boil.
It will up your amount of sparge water.

As NCBeernut says Beersmith does not adjust OG based on boil time. If you want to see the effect of a longer boil on your gravity you have to know your boil off rate and then manually change the amount of your batch size to your anticipated final volume.

At least on my beersmith, if you adjust the boil time (near the efficiency number at the top of your recipe) it will adjust the amount of wort you need to collect at the beginning of your boil. Lower the final batch size if your intent is to up OG via a longer boil.

-whoops, looks like NCBeernut already stated this above!
