I m using a Document module in that i created a user and assign a role with edit and veiw permission to that but when logged in with that user i am not able to upload the document from desktop

but that is working when i applied the administrator role to that  
Is that a problem related with the editor or any other setting required

The Documents module interacts with the permissions set in the File Manager (view the File Manager tutorial for further information) which allows you to specify which users have permission to download a particular document.
