I found water today on a shelf at the entertainment center.
I was in a panic since my built in computer ($$$) is right under that window. No damage fortunately.
There is a small window right above it.
I discovered the drains at the bottom are just pressed in slots (2). That window did not get a good pressing and the slots are VERY small off center hits. Fungus had grown in the grime and plugged the poorly made drains. I cleaned them with a pocket knife, but I plan on opening them up as soon as the rain stops. I am also checking all the other windows as well.
