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.

Kids World demo -- In TidBITS-255, I reviewed Kids World, a kid's program for creating animated screen savers. Those wanting to give Kids World a trial run can check out the demo, which offers a good idea of what using Kids World is like, but only gives access to Backyard World and the painting tools. If you try the demo, you can see a special animation by positioning the cat and dog close together. [TJE]
