Thank you very much to you all for your answers. At least I don't feel like a complete newbie as I can see there is not a straightforward solution to this problem.

I think the same way as GSquared - that this seems to be a problem inside SSMS and since my database is running on windows 2008 server running in English (both the OS server and the SQL Server) I wonder if the results would be the same should the database and OS be in Spanish... maybe I will try this but those being in English is a requirement from our ERP vendor.
