Microsoft Internet Explorer 3.0a -- Although I use a variety of browsers to view and test Web sites, I'm using Microsoft's Internet Explorer with increasing regularity. With the release of version 3.0a (PowerPC-only, alas) last week, Microsoft has resolved problems with deleting cache files, repeatedly reloading some Web pages, Challenge Response Protocol (used when accessing secured pages), and loading Java under MacTCP. Minimum and full install versions are available, ranging in size from 2.1 MB to nearly 8 MB. [JLC]
Option-Click AirPort Menu for Network Details
If you hold down the Option key while clicking the AirPort menu in Mac OS X 10.5 Leopard, you'll see not just the names of nearby Wi-Fi networks, but additional details about the selected network. Details include the MAC address of the network, the channel used by the base station, the signal strength (a negative number; the closer to zero it is, the stronger the signal), and the transmit rate in megabits per second showing actual network throughput. If you hover the cursor over the name of a network to which you're not connected, a little yellow pop-up shows the signal strength and type of encryption.
