I'm talking about the blocks around it, and the window is a texture...
Here is diagram.. I made... it's really horrible... I hate paint.

There are 8 visable blocks, and one in the hole (either a block of glass, or a block with a texture on it.
As for the new screenshot, I have it right now, I'll go and ask a team member from the bbs team If I may post it publicly here... :S
EDIT: actually, yes, you need five including the window frame, if it is all togeather like you described it, but sometimes it happens to be like the diagram above... which sucks

Anyway, still, 5 times 200.
