Microsoft has released Skype 6.7, which completely overhauls the telephony app’s search feature. Now you can enter a term into the toolbar’s search field, and it will bring up a list of relevant conversations, as well as enabling you to explore your entire conversation history. A number of issues have also been resolved, including Skype hanging when closing the application during a call, being unable to hang up a call with the keyboard shortcut, and duplicate messages to Facebook contacts. There is an existing known issue with Mac OS X 10.7 Lion where the app sometimes crashes when clicking on profile pictures or file transfer icons. If Skype’s automatic update feature hasn’t yet gotten you the new version, choose Skype > Check for Updates, or download a copy from Skype’s Web site. (Free, 40.6 MB, release notes)
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.
