What have I done? Now when I'm trying to fill in forms and skip to next bit using tab key it keeps swapping between windows of everything I've got open instead. I've done it before, but only fixed it by accident then, and it's getting on my nerves now. Anyone know anything about computers??
Not to sure, but could be something to do with the accessibility options in control panel. Maybe sticky keys or something. Check in there and see if you have changed anything.
That's Alt + Tab. Sounds like you've got StickyKeys on, which means you only have to press keys like Shift, not hold them. Press Shift five times quickly to bring up the StickyKeys box, and then press Cancel.
