The only difference is between Excel97 and later as 97 does not support
callbacks, so they are emulated.

The API timer stops the system getting bogged down, ad Ontime will do, and
it provides < 1 sec granularity.

It will fail if there is anything wrong in the code when callback triggers.
This is an unfortunate consequence of the beta Google groups, this failure.
If you like I can mail you a working workbook.
