Ethernet Update for Recent Macs -- If you're experiencing Ethernet problems with an iBook, a FireWire-equipped PowerBook, or a slot-loading iMac or Power Mac G4 shipped since November 1999, Apple may have a fix for you with its Ethernet Update 1.0. The update is intended to improve Ethernet reliability on uncommon network setups, usually including large unswitched 10Base-5 (thick Ethernet) or 10Base-2 (thin Ethernet) segments with unusually small interpacket gaps (the delay between transmission of Ethernet data packets) or dropouts due to high network activity (after repeated attempts to retransmit data have failed). The update is a 2.5 MB download; it requires Mac OS 9.0.4 and replaces the Mac OS ROM file - but if you aren't experiencing Ethernet trouble, there's no need to download this update. [GD]
Avoid Long Hierarchical Menus
If you right-click (or Control-click) on some item, such as a file in the Finder, and one of the sub-menus has many options (Open With is a frequent culprit), it may take several seconds to open, even on a fast machine, which is annoying if you did not actually want that sub-menu.
The trick is to not pull the cursor through the menu, but in a curve around it, so the cursor does not touch any menu items until lower on the list where you wanted to go.
