I think you have to at least choose the last Log backup or both of them, but not only the first one, to get the STOPAT clause generated. At least that's the way it seemed to work for me.
However, I still get errors when I try to run it. Not knowing anything about this particular syntax for restoring a database, I can't off the top of my head figure out what's wrong with the generated statements.

>>OK, the Restore didn't run correctly, even though the commands looked ok ... got a few errors, but I may have goofed something up. It's late.

Then press Script button and there is no STOPAT option in the generated command. The Restore failed, though, saying I have to select STOPAT or NORECOVERY option. But I just did?
