Each time I try to download any kind of data file (.doc, .mp3 whatever) from my local computer, Internet Explorer 7 on Windows XP presents me with a dialog box, called "File Download - Security Warning". It is asking whether to Save or Open the file directly, or Cancel the download. The checkbox "Always ask before opening this type of file" has disappeared. There seems to be no way to get rid of the dialog. The file type available through Folder Options | File Types | Advanced does not provide any way of changing this, only the checkbox "Confirm open after download", which obviously does not help. Oh, boy! I have tried looking into the post with "Turn off Open File - Security Warning" on this site, but that only seems to work for executables, and does not apply in my case, or maybe I'm doing something wrong. Can anybody help?
