Are you just launching the games yourself? Not using other Multiboxing software?

The only thing that comes to mind is something that popped up the other day for a player.

Get the game back to the default settings. You can do that temporarily and not lose any customization you've done.With the game closed please rename your WTF folder to WTF.bak and INTERFACE folder to INTERFACE.bak. Delete the Cache folder entirely. These hold setting info and temporary cache files that will be recreated by the game the next time you launch. Renaming them allows you to rename them back later if this step doesn't resolve anything.
NOTE: Please also make sure to remove any and all addon auto-installers or auto-updaters you may have, as those can automatically reinstall addons for you, possibly causing further issues.

See if that does anything.

I am launching wow with a batch file only. I tried manually, same problems.
And i did a clean install of wow by donwloading the client without installing some addons. Same things.

And i am using keyclone but even if i don't launch keyclone the problem still there.
