Leaking windows and walls

Oh the joy. I went to bed last night and could hear a noise. Thought it was the cat doing a noisy manicure. Turned out to be water dripping from the window frame - not the window that opens.  Had to get a bowl and towel, and then move bedrooms so that I could sleep.  Lay awake worrying for ages.  It's not good when the house lets you down, even in exceptional weather conditions.
Going off to destroy icicles now - that might make me feel better!
