Moo! The Musings of a Plaid Cow

If you create a filename in the Finder which has a very long extension, you will not be able to change it using the Finder. (An extension is defined by an number of characters after a period in a file name which does not include spaces.) In this case I am starting with `file.with_a_very_very_long_extension_name_or_at_least_a_period` and renaming it to `file.txt`. Upon renaming it, the error is shown:

Since the existing filename is so long and the dialog does not resize, the `Use .txt` button has been pushed off to the left. Adding to the misery, the standard Command-U shortcut will not operate the non-default button and you can’t use keyboard navigation (Tab-Tab-Space) to activate the button since it was not actually drawn on the dialog.
