When I have an Excel file open...and I want to open another file, I click on :

File
Open
then, I select the file and open it

Here is the quandry:

ALL OF A SUDDEN, THE LISTING OF FILES IN THE DEFAULT LOCATION (C:\Documents
and Settings\user\My Documents\Excel) IS NO LONGER IN ALPHABETIC ORDER.
SOMEHOW, THE ORDER HAS BEEN SKEWED.

Opening up the above folder does have the files listed (correctly)
alphabetically; but, the "OPEN" screen from Excel lists the order of the
files differently!

How did this occur?
Can it be fixed?

Thanks,
