Well, that would seem to make sense, if I had entries in the workbook
that would require calculations. There's no calculations to be made.
I have done this though. I copied all of my modules into a new
workbook I called macros. Renamed the personal.xls to personal_old.xls
and macros.xls to personal.xls and problem's gone.

spooky!

Thanks for your help everyone!

Now if I can only get those trace dependent and precedent arrows to
show up.
