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)
Single Time Machine Backups
Tired of Time Machine running all the time? You can turn it off in the Time Machine preference pane, but still initiate a single backup by choosing Back Up Now from Time Machine's menu bar icon. Of course, your backup is much less likely to be up to date, but Time Machine won't be taking any resources while you're trying to work.
