I write in two languages so I setup the US International keyboard every time I install windows. My problem now is that the US international works for a while and then it does not works again. For example, if I press the ' and a vocal letter I should get an accent like áéíóú. Well now it works but every now and then I had to install the US keyboard, switch to it, then switch back to US international and delete the US keyboard just to make it work. I just set the other users of this desktop to the same keyboard, hopefully it will stick and not change again. Any ideas on how to solve this if it happens again?
