Microsoft has released Skype 6.19, which adds support for using VoiceOver to select recent searches from the Add Contacts search field. The update also fixes several reported crashes that occurred when sending and receiving files, fixes a crash that occurred when waking from sleep, and ensures that older Mac desktop machines successfully return search results when searching for messages.

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.
