Has anyone else been having an issue where their Apple Wireless Mouse keeps skipping if their system is doing something that (apparently) is very processor intensive? This has only been happening to me since I updated to 10.4.3. Even the act of moving files from a CD to my hard drive will make it do this; the mouse becomes very unresponsive, moving the pointer only in jerky steps across the screen. Also, my Apple Wireless Keyboard keeps losing it's connection while this is going on. It's very annoying.
