Ahh! I froze my orchid!

[Orchidreamer]

I have a large Rhynchostylis gigantea that surprisingly nearly doubled in size over the past year, despite the specie's reputation as a slow grower. After summer, I moved it inside and it hung by the window.

Two days ago I inspected the leaves and they were all covered with transparent and watery brown patches. The poor plant looks terrible! I had to cut off the newest leaf because it looked like green mush. I quickly moved it to the warmest room in the house. Over the past 2 days, some of the damaged areas became pitted, while others seem to be getting more and more "watery." Even worse, today I discovered some new light brown patches that weren't there two days ago.

Lesson learned: never put orchids by a cold window. Especially a warm-growing one. I should've known better.

What are your experiences with cold-damaged orchids? I'm really worried it's going to lose its leaves...this is the 1st time I've had a cold-damaged orchid.
