I think this is a familiar question, but since I don't have an answer, I'll ask it here.

Since the halacha is that Hadlaka Oseh Mitzva (the conditions at the time of lighting need to be adequate), how can one put a menora (chanukiah) in a glass box outdoors to protect it from blowing out? At the actual time of lighting, i.e. before the box was closed, the candles were not in a position to last the required half hour b/c of the wind. Only once you close the glass will they be OK - but Hadlaka Oseh Mitzva so it should be too late.

I was told that many achronim deal with this question. I would be happy if someone could bring links to sources or atleast sumamrise the various opinions.
