Barbara,
Thank you, you were right.
As a filename I was using C:\WINDOWS\DESKTOP\filename
and this worked OK in some machines (those with the Windows in English),
but didn't work in machines with the Windows in spanish.
In the spanish version the DESKTOP is called ESCRITORIO and that is the name of the folder.
Thank you again.
Eduardo
