Hanacha Oseh Mitzva (Shabbos 22b-23a)

The gemara says that if you say hanacha oseh mitzva then if you have a lantern that was lit from Erev Shabbos and it stays lit until Motzei Shabbos then you would have to put it out, pick it up, put it back and then light it. Someone asked this morning: what exactly is required for hanacha oseh mitzva? Do you have to pick up the menora each night before you light it? If so then why shouldn't you have to pick it up and put it back after it's lit?

There is a machlokes between Rashi and Tosafos in this case why the lantern was lit on Erev Shabbos. Rashi says it was for Chanuka and Tosafos says it was for Shabbos. I saw this morning (I think it was in the Sfas Emes) that according to Tosafos the questions aren't so bad. As long as the menora was initially put there for the mitzva of Chanuka then that suffices for hanacha oseh mitzva once the menora is lit. However this case is where it was lit for Shabbos so you need a hanacha (even if it's before the candles are lit) which is l'shem neiros Chanuka. According to Rashi though the question remains. It seems that according to him, if you light the candles on Friday night and they go out that night then Motzei Shabbos you can just relight them without moving the menorah even though hanacha oseh mitzva. If the candles stayed lit though until you were ready to light on Motzei Shabbos then you must pick up the menorah to show that the hanacha is for the mitzva.
