Why does Microsoft Internet Explorer (IE) 6.0 prompt me for an action when I click a .tif file, even after I've cleared the "Always ask before opening this type of file" check box?

A. When you select a link to a .tif file in IE, the browser will always prompt you to either open or save the file unless you clear the "Always ask before opening this type of file" check box. However, a bug in IE 6.0 can cause the browser to lose this setting, forcing you to make a decision each time you access a .tif file. To resolve this problem, perform the following steps:

  1. Start a registry editor (e.g., regedit.exe).
  2. Navigate to the HKEY_CLASSES_ROOT\.tif subkey.
  3. Double-click the Default value and change the value data from TIFImage.Document to Imaging.Document.
  4. Navigate to the HKEY_CLASSES_ROOT\.tiff subkey.
  5. Double-click the Default value and change the value data from TIFImage.Document to Imaging.Document.
  6. Close the registry editor.

The problem occurs because TIFImage.Document and Imaging.Document share the same class identifier (CLSID) but the reverse lookup points back to only Imaging.Document when you access a .tif file. Hence, IE 6.0 ignores the registry settings for TIFImage.Document.
