Am using an HP wireless keyboard and wireless mouse.  HP has replaced
the receiver, mouse and keyboard, and I'm still experiencing this
problem:

About 10 times per day, I will be typing away, and I'll look up to see
that the keyboard (I guess) has generated 17 or so repeated characters,
and has ignored the actual characters I've typed.  It's always 12-16
characters, and never, say, one or two extra characters.

I also seem to expereince "missed" characters that I've typed - when
this occurs, it's generally two or three characters.  I used to think
that I had misstyped, but lately I've become convinced that I've typed
ok, but the app never received the keystrokes.

I'm running on an HP Presario R3000 (3+ MHz) with Windows XP SP2, 1.5GB
memory.  I've downloaded and installed all the latest Windows updates
that I've been offered.  I'm not sure if I have the latest drivers for
a wireless keyboard, nor am I sure how to check this.

Is this a typical problem with wireless keyboards? Does anybody have
any information on what might be happening?

Thanks...
