I've noticed that UDFs won't auto-calculate, and I can't figure out why.
Even F9 and Shift+F9 will not force manual recalculation. The only way I can
get them to rerun the code in the UDF is to select the cell, click in the
formula bar as if I were going to edit the formula (or use F2), and enter
the formula again.

This leaves me with one simple question:
How do I get my UDFs to autocalculate, just as normal Excel functions do?

Thanks so much for all your help!
