    Keyboard autorepeat misbehaving - Ideas?

    Hi all. An "interesting" problem!

    We all know that if you press a key and hold it down it "autorepeats", hold down "w" and you get "wwwwwww". Now, if you look under the hood you'll see that the application gets a series of events. A single press gives "keydown keypress keyup" and if held down so autorepeat cuts in you get "keydown keypress keydown keypress ..... keyup". Or you should.

    One of my new Windows 7 PCs instead gives "keydown keypress keyup keydown keypress keyup .....". The difference is subtle and invisible to most programs, but fatal to games. To a game it looks like the user is hammering the key rather than simply holding it down. That kills the game.

    Has anyone come across this, and does anyone know what causes it and how to cure it? I've spent all evening googling and apart from an obscure bug with the Opera browser I can't find a solution.

    The PC is an Acer laptop with Windows 7 home premium 64 bit. The problem is NOT hardware related, it happens with a USB keyboard or the built-in keyboard. The keyboard driver appears to be the same Windows driver as all my other PCs. Filterkeys isn't turned on, autorepeat settings are normal. I've scanned for malware using Windows Defender Offline (Microsoft Security Essentials is running). It is probable that this behaviour has been there since I got the PC (new) but it only showed up when I tried playing Minecraft (which uses WASD for movement). Other games have the same problem though they exhibit different symptoms, depending on how they react to button bashing.

    Ideas?

    OK, finally solved it. Nothing to do with the drivers. My daughter has dyslexia and uses a program "global autocorrect" which once used loads every time at startup and intercepts the keyboard, replacing autorepeated keys with individual keystrokes. A very good program if you're dyslexic and you can disable it for specific applications so all is now well.

    Thanks for posting back, this is something I suspect no one would have arrived at.
