The top taskbar (or whatever it’s called) on the right. I have Quicksilver, menumeters info, Bluetooth, Airport, Sound, Battery, Clock, Quicksilver. Put the cursor over anything except Airport, tap the pad and the appropriate information appears instantly. But not Airport. It takes a leisurely 2 or 3 seconds to display it’s menu and list of networks. It’s as slow on the other mac. Why? Windows does it faster. I know it’s a tiny detail but sitting here hopping networks that delay is driving me nuts. Is it really stressing the mac to have it scan and update any list faster?
Maybe instead of scanning all the time, it’s doing scan on demand. How often do you switch wireless networks?
