I don't want to info overload you -- and everything above is absolutely right. (not surprising given the sources!) Although I wish I could grow my orchids in the middle of the table or on the coffee table like you see in the magazines, they need more light.

I'd move yours closer to the window. If it is southfacing you will want to either be slightly further from the window or get some sheer curtains. (I use sheer curtains on my south facing windows and it works wonderfully.) Phals don't like hot/direct sun (they get black burned spots on the leaves). A good rule of thumb is that if the leaf feels hot, it is probably getting too much direct sunlight. Try moving yours closer and see what happens. Keep us posted.
