Split Lines disappearing...

Hello,

When I use the Surface-Extend command, it causes a split line to disappear.  I'm starting to sound like a broken record because during the switch from 2009-2010, the knit feature changed how it handled split lines, and now Surface-Extend apparently has changed.

The reason why I care is that now my part fails, and I have to spend about an hour fixing it.  Which is fine, except when I have tens if not a hundred parts where this is going to be a problem....

I expect that when I upgrade from 2010 to 2011, that my parts SHOULD NOT all of a sudden fail. ...sigh...

Is there any way to make surface extend not delete a split line?
