Twitterers who don’t fear Adobe Air may be intrigued by news of the release of TweetDeck 0.37.3. New in version 0.37.2 is support for deck.ly, TweetDeck’s new, semi-ridiculous system for allowing tweets longer than 140 characters (the 0.37.3 version, currently available only via direct download from TweetDeck’s Web site, adds an option in the preferences to turn off deck.ly). More satisfying is the software’s added support for Instagram image previews. Also new is an upgraded version of the Squiggly spellchecking library. The update fixes several bugs, too: problems where punctuation in searches prevented them from working, a bug with Facebook’s login screen, and an issue with Twitter lists not updating properly.

Turn Off Filename Extension Warning
In Leopard, Apple fixed an annoying aspect of working with the Finder in Tiger. Previously, if you changed a file's extension, the Finder prompted for confirmation. But since no one has ever accidentally changed a filename extension, Apple thankfully added an option to turn that warning off in the Leopard Finder's preferences. Choose Finder > Preferences, and in the Advanced screen, deselect Show Warning Before Changing an Extension.
