We have an infuriating problem with a (Vista/Dell) laptop. When an external (Logitech) USB keyboard is attached to it, it regularly starts repeating key presses. When the user recently deleted an Outlook message, it deleted them all! When typing a message, suddenly it will start repeating the last keypress about 30 times (it varies).
It's not a mechanical issue. We've switched the keyboard out four times. Even tried a brand new one one. Every time it's the same. Also, the keyboard works fine on other machines.
The problem doesn't arise when the laptop's own keyboard is used - even if the external USB keyboard is still attached.
I'm stumped? Any ideas. Not using an external keyboard isn't an option due to our health and safety policy (...don't ask...).
