Benny,
cbWndExtra is declared as an int in the MS header, so there is no space to 
reserve. Usually it it used as a pointer to the window specific data 
structures.
A possible reason for Daniels problems may an error in the declaration of the 
WNDCLASS structure. Perhaps he should download the real thing from the MS SDK 
....

Regard
Karl

Hi Daniel,

I think you forgot to reserve the space for that data. In the
initialization of the WNDCLASS struct for the DocWindow, do

    wnd.cbWndExtra = sizeof(LONG);
