I have written macros for years, storing them in personal.xls.

Suddenly, after a powerglitch yesterday just as Excel (2002 SP3) was
loading, it will no longer load personal.xls.

Other files in the XLStart directory load as expected.
If I rename the personal.xls to a different filename, then it will load
fine, and the macros inside also behave just fine.
If I create a new macro to be saved in personal.xls, save it, and close
Excel, the new personal.xls will not load when Excel restarts.

What happened?

TIA,

Ken
