IME Not Working In Windower 4 Under Windows XP

Hey guys,

Not sure whether anyone else is having the same issue.
I was able to type Japanese with IME plugin before Windower 4.
Used MS Appcale to execute the windower as Japanese language and it worked just fine.
This method seems no longer working with Windower 4.
Just wondering if there is any solution to fix this.

Thanks a lot in advance.
