I found a very strange instance.

When I double click a excel file, for example form the path
"D:\Profiles\jimmyl\My Documents\05. ABC.xls"

Excel with Open the file "D:\Profiles\jimmyl\My" first and result in file
not found, and then open "Documents\05." and result in file not found, and
then
open the file "ABC.xls" and result in file not found. At last it will open
the file. How come windows treat the space as a space and separate the
opening of a single file?

I found that it may be related to the Windows Explorer file associate
setting. The following setting is found.
Action - &Open
Application used to perform action - "C:\Program Files\Microsoft
Office\OFFICE11\EXCEL.EXE" /e %1
Use DDE
DDE Message - [open("%1")]
Application - EXCEL
Topic - System

Any ideas to fix this problem? And I try to delete the "%1" after /e but it
fail, why? Any can help?
