I'm coming a bit late into this conversation (just getting back
from vacation), but if you are doing this on mouse clicks, why
not just use the binding mechanism already in Tk?  You can use
that from C as well.  [winfo pointerxy] isjust %X and %Y.

Indeed.  ffidl is fickle though - very easy to blow up in your
face.
