Every now and then I have this trouble with my keyboard where it changes the language and I get characters I don`t expect, for instance, right now if I try to type a Question Mark I get É, if I try a bracket I get ç. Itès obviously switching to French on the fly, the only way I can figure to fix it is a reboot. This has been happening for years with many keyboards and both XP and Vista. There has to be a way to change it on the fly but I canèt figure it out.
