My map is leaked but cannot point out how

[_Meitsi_]

I loaded pointfile and it points to one of the windows, but i just cannot figure out _how_ is my map leaked... :S The window covers the whole hole... Should it be covered with nodraw from the back too? Could someone explain this?

Okay, solved the problem... Got just cover the holes from back with nodraw... Maybe models are not allowed as "hole coverer"...

Indeed models do not block visability.
