OOPS - I need to follow my own advice and double check every statement  
to ensure it works as expected. In particular using just ENUM alone  
will start numbering the constants from 0, not 1 as I had assumed.  
DUMB - do not assume, check!. The effect in the sample to you Brian  
was that the _toolsWnd constant had value zero and the WINDOW  
statement for it would not work. Sheesh.  Anyway, the correction is  
ENUM 1,1 so that the constants start numbering at one and go up by  
one, which is what you want for window numbers.
