A question about Xee: It can easily be set to be the default application for various types of files. But it seems to be difficult/impossible to reverse the choice! Xee has a list of perhaps 50 file formats it can open. In Preferences>Formats, you can Select all, and it does indeed select them all (and seems to actually take over at least those files I have examples of). But Deselect all does nothing. Each file type has a selection box. Some of them (e.g., Fax Document) can be unselected. Others (e.g., JPEG Image) do nothing if you unselect them. What controls this seems random - about half the various "raw image" formats can be deselected.

Using Finder to set JPEG files back to using Preview works, and if I exit and reenter Xee the box is deselected.

I think I saw the same behavior with Unarchiver, but in that case when I exited and restarted, it let me Deselect all successfully (and I can't swear that it actually ever failed to work.)

Xee Version 2.0 on OS X 10.4.10.
