This has been pissing me off greatly. I recently upgraded to 64 bit Vista from 32 bit. I have 2 inputs, English and Chinese. Before in 32 bit Vista, I can press ctrl+space to switch between languages. Now in 64 bit, I can press ctrl+space to get to Chinese, but I can't do it backwards. Apparantly the toggle is ctrl+alt. I can't change that under advanced key settings. How can I change it? This has pissed me off so much I almost smashed my computer.
