Mac OS Runtime for Java -- Apple has posted a pre-release of Mac OS Runtime for Java, which is essentially designed to put a Java virtual machine into the Mac OS. I can't honestly recommend this release to anyone but Java and OpenDoc fanatics, but the runtime does allow users to run Java applets in a stand-alone viewer and within an OpenDoc document. It runs on any Mac with a 68030 or better and System 7.5. Apple says the Java runtime will work with the shipping version of Cyberdog 1.1 (due very shortly), but it doesn't work with previous versions, including Cyberdog 1.1 betas. [GD]
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.
