Phrag Help Needed!

[Becca]

I have a Phrag. boissierianum that I am worried about and needs some help! I'm not quite sure what is going on with it, I was thinking stem rot....but I am 99.9% sure I haven't gotten any water in between the stem and leaves. The leaves are turning a mushy brown starting at the inner part of the leaf and then moves to the outer part of the leaves and it is on both new and old growth and the lower leaves only, but I think in one of the pictures I see a hint of the brown on the stem. The roots seem happy, it is potted in bark and I acquired it this last April. I do let it sit in a saucer of water to sip water from but I don't leave it like that all the time. I'm hoping someone can help me save this baby before I loose it or it get's any worse!

Oh, and I guess growing conditions would help....this grows on an East facing windowsill along with several other orchids such as some compact Cattleya hybrids and temps are in the intermediate range nothing below 68 at night currently and around 80 during the day.
