Bluetooth problem, ugh

[QueBert]

I have the Logitech diNovo keyboard+mouse setup. Did a clean install of XP, put the latest drivers for it, now I'm always having to rediscover both the mouse and the keyboard. On my previous XP install, I'd have to do it from time to time. Now, I might have to rediscover 3 times a day. It's very annoying as I have to keep a backup keyboard plugged in at all times so I control the system to get the stupid logitech software to kick in.
