Hi liadavide,

And thanks for your your responses.

1. As it happens with text editors then it is Windows, not IE, this would be confirmed by the fact that FF suffers the same.

2. We can forget Opera as a useful test now

3. If safe mode works then that is when you are in Windows' basic default mode. That is very interesting because it suggests that something is loading in normal mode that is causing this, rather than some sort of fundamental corruption of the Windows operating system.

Equally importantly, it tells us that you do not have a hardware problem with the keyboard controller chip on your motherboard. OK, you would probably not get that from a USB keyboard either, but this is double confirmation.

I am pretty sure that the keymapper you used just looks at the default Windows file as well, which is why it didn't show any anomalies?

4. The onscreen keyboard uses the basic Windows setup as well, which seems to confirm what we have concluded from the above. That this is probably related to your specific, personal logon, using a physical keyboard.

5. From what we have determined, I do not think that this is a browser "thing" at all, but we can easily prove that

OK, if you log in as administrator and create a new account "AOTEST" or something? Let this be an "all users account". Then try a text editor or internet browser application.

Please be sure that this new account starts your firewall and anti-virus when you boot up in it.

My hope is that your new (test) account will allow the keyboard to function correctly. If this is the case then it means that your regular account has become corrupted in some way or another.

Please do not worry about your existing account, the new one won't affect that, and if this works, we can use it as a base to build your old account back on.
