Shift + i causes "paste" instead of letting me type a capital I

Like the title says, I've been plagued by the somewhat well-known bug that causes Dreamweaver to handle the key stroke "shift + i" like the "cmd/ctrl + v" command. I don't know what caused this, but it has persisted throughout various updates. Whenever I try to write something that contains the capital letter I, Dreamweaver instead pastes the contents of my clipboard into the current cursor position.
The only temporary workaround is to copy a capital I somewhere else and then paste it in my Dreamweaver document. This only works as long as there's nothing but the capital I in my clipboard, of course.
I've seen people discuss this bug in some forums and the solution was to edit an xml file, but I'm not comfortable changing the core settings of Dreamweaver just to fix this weird bug that no one else in my office is experiencing.
Has anyone else experienced this?
