Vista Tutorial - Open IME" & "Reconversion" option on context menu, How do I remove

I have two options on the right-click (context) menu of any edit-able text
field (such as the Address Bar, Run..., or Notepad). I do not know what
created these options, nor do I know what they do. They take no noticable
effect when I select them. They appear at the bottom of the menu (below the
"Select All" option) in their own group (underneath a seperator). One option
says "Open IME", and the other (just below it) says "Reconversion". The
Reconversion option has never been available, that I have seen.

When I select the "Open IME" option, it changes to "Close IME" the next time
I open the menu. But other than that, I see no effect.

I don't have any language packs involved on the machine.

Can someone tell me how I can remove this?

Thank you

Well, I see this is an old post, but I was hoping for a solution to this...
Hopefully someone knows a way to disable this feature. I will never need to write right to left...
The context menu is simply too big and full of features I don't use.
Just look:



Please help
