I am using Office 2003 on Windows XP.

If I create three identical macros and call them "a1", "aa1", and "aaa1",
only the last one called "aaa1" will work. I cannot go to
Tools-Macros-Run and run the first two macros.
I can step through them at design time, however.

Are there new name restrictions in Office 2003?

The macros I used are posted below.

Sub a1()
Cells(5, 5).Select
End Sub

Sub aa1()
Cells(5, 5).Select
End Sub

Sub aaa1()
Cells(5, 5).Select
End Sub
