No, the docs faded from my memory.

The reason for the confusion was, that I have used something like
SetWindowLong(hwnd,GWL_USERDATA, (LONG) pData);
to store  instance specific data. This long word is always available and one 
can safely set cbWndExtra to zero. You can obtain a news message related to the 
problem from

No. Read the docs.
