  I did not research the code, bug here is one more *very* funny possibility -
  fgBits++ overflows and sets ftBits to 0.

+ David, it's better to add your comments to the bug description.
+ Here they are:
+ 
+ ****************************************************************
+ As I reported, I put in some trace's in the innermost x & y loops.
+ The problem is that the entire theImage is filled with zeros. Both
+ xmax and ymax are 32 and I can't belive the compiler is so broken that
+ the ++ operator fails; if so, we have more problems here, ground
+ control.
+ 
+ So only your last possibility seems reasonable.  On the other hand,
+ why can't a cursor mask be all zero's?
