Word 2003 Application Error

[Richard]

I have an end user that get's the following error message when he tries to
open a specific document:

"an error occured in sending the command to the application"

I am able to open the document just fine and so are other users. Thoughts
on how to correct this?

Have you tried repairing the user's installation of Word/Office?

Also, does it make a difference *how* the user tries to open the document?
By double-clicking? Via the Open dialog box?
