I have multiple Windows 7 pcs that are unable to upload PDFs to websites. When we try, we get a message that we can only upload pdfs. The problem is, we ARE uploading PDFs. This happens on more than 1 website.

I found that deleting mimetypes.rdf fixes the problem. However, the problem comes back and I have to delete mimetypes.rdf again.

Does anyone know how to figure out what is causing the mimetypes to keep changing? Is there a way to stop the mimetypes.rdf from being overwritten?
