For some reason, if I go into Time Machine, my iMac G5 (2 GHz ALS) completely loses contact with my Apple cordless mouse and keyboard. They work fine otherwise. If I connect wired versions of the KB and mouse, there is no issue. I've tried batteries, plist deletes, reformat TM drive, cocktail, etc and anything else I can think of, but nothing works. It makes me crazy because they used to be fine in TM...now they just don't work anymore. Any thoughts would be appreciated.
