Hi all,

When I copy or move a worksheet. I received the message box:
"A formula or sheet you want to move or copy contains the name'a1', which
already exists on the destination worksheet. Do you want to use this version
of the name?
.. To use the nam as defined in the destination sheet, click Yes.
.. To rename the range referred to in the formular or worksheet, click No,
and enter a new name in the Name Conflict dialog box"
Note: These range names is not defined by me. They may be a macro virus. I
scan my PC, there is not any virus found. I use MS Office 2003. It have
licensing.

* Example: I have a worrksheet name is "a". I use copy or move command to
copy this "a" become worksheet "b". But I can not make a copy of worksheet
"b" by using copy or move command, i received the message box above when i do
this. I can make a copy of worksheet "a" by using copy or move command.

Please tell me what happen.
