Just got my logitech MX bluetooth keyboard and mouse setup yesterday. The computer will not boot up when the USB/keyboard connectors are connected. The computer will hang up on the loading screen. If I disconnect them, and restart, the computer will start fine. I can then connect them and start using the mouse and keyboard. Needless to say, this is irritating. Has anybody experienced this problem? I'm using an HP Athlon 3000+ with Windows XP and SP1 (haven't gotten around to upgrading to SP2, but might give this a shot this afternoon). I haven't posted to logitech's site yet because I need the model numbers and all that (I'm at work), but will do this later if nobody here has any ideas.
