The latest installation of iTunes/QuickTime seems to have killed my installation of AlternaTiff (my preferred Tiff viewer for USPTO patent images). Reinstalling AlternaTiff didn’t work. QuickTime was still taking over. Argh.
Then I found instructions on AlternaTiff’s website regarding how to beat QuickTime into submission.
Update (2005.12.09): My problems came back (in FireFox). Deleting npqtplugin6.dll from "C:\Program Files\Mozilla Firefox\plugins" fixed the issue. Apparently, the QT plugin was overriding the AlternaTiff plugin (npzzatif.dll).

Make SURE that EVERY TIME that you actually, intentionaly use Quicktime and it gives you the dialog box “Some MIME types previously associated with quictime…..” you answer NO. Otherwise you will have to go through the process again. Believe me, this is even worse if you work in an envirnoment where you don’t have admin priveleges on the machine at your desk. You have to persuade the HelpDesk to change your priveleges, to allow you to have quicktime to edit your preferences so QT won’t try to open TIFFs. Macheads can hear no wrong where Apple is concerned, but Quicktime wants to be as invasive and all-conquering a media device as any Microsoft product. Sorry, I had to vent here
I have used AlternaTIFF. But, I prefer CPC View (http://www.cartesianinc.com/Products/View/TIFF/) for viewing TIFF images. It seems faster and has more features.
