Thanks for the replies, they've been helpful. I've added the executionTimeout setting to my web.config and set it to an hour. This setting was missing completely from the config file, so I'm not sure what happened there.
Basically what I'm after is a way for my clients to upload large files to me (databases etc) as an alternative to email. I don't intend using the Repository module as a frequent use, public upload module. I only intend to us it in times of technical support when I need to get a large file and email in inappropriate. To this end, I don't really need (or want) to let clients know that I've "rejected" their upload, when all I've really done is receive their file, processed it and now need to delete it from the site.
Perhaps there's another module better suited to this purpose?
Another thing that seems like it could do with a bit of refinement is the skins. The skins for the module are a great idea, however for a simple file upload, I've used the "filelist" skin which seems most appropriate. The problem with this is that the user needs to check the "All" checkbox before a file can be uploaded. Is there a way to remove this category, and just have a default category that you don't have to prompt the user to select?
Basically, I just want the simplest, easiest way to upload a file, with a minimum of mandatory information - name and filename would be great.
Thanks and best regards,
Rod
