Thanks for replies..

I've already got the basics covered;
spare brand new wired and wireles keyboards,
when I can remember which boxes I stored them in.

Fod and drink is never alowed in my litle computer den,
and dust hasn't setled on the keyboard.
[powerful air bulb pufers and brushes.]

My best gues is a setings glitch due to lengthy time since last rebot.
But I dont have time for software troubleshoting right now.

Hopefuly a rebot wil clear it.
If not, crack on loking for a spare keyboard.

I'm just amused by this malfunction,
and curious what's causing it.???
