ANNOYING problem with typing foreign language

This problem is really bugging me. When I type korean in Word2007, one korean letter is assembled at the TOP LEFT CORNER on my desktop FIRST and then shows up on MSword once the korean syllable is created completely. Im running 64bit vista home and this problem suddenly happened today without warning. and YES, i googled this, and i CANNOT find a solution.

It's EXACTLY like this person is experiencing here:

I want to write korean the "regular" way (how annoying would it be to type 1 word first before it shows up on Word?). I really need to get this problem fixed because I have to type up something for my korean class and its just bugs the hell out of me that I can't see each korean letter typed on my paper.

I attached a screenie to show you guys my issue. What is the black box in the corner? If i hover my mouse over to the green arrow, it says "Finalize the string"

thanks!

Heres a video of my problem.

Also, I noticed that this problem ONLY occurs in MS Word (PPT and others work fine), AIM, Pidgin, and Y! Messenger. I'm not sure about other programs.
