IT won't dock to MS Word

For some reason, my IT just spontaneously stopped docking itself to the bottom of my screen. It was fine and then all the sudden whenever I'd start typing in my Word document, the IT box disappears. It's still running in the background because my expansions still work, but I can't see it on the bottom of the screen. I've tried linking, restarting, trying it in other programs, etc. Is there a simple solution to this? Thanks.
