Winamp brakes japanese input scheme
 

OS: Windows XP up to date
input scheme: Japanese MS-IME2002

As soon as I open winamp and play a song all the options from the input sheme task menu are disapearing and options can only be changed from the Settings menu but they no longer have any effect. When I close winamp it works again.

The input scheme is broken for all applications not just winamp.

any idea what causes that? Never had problems before installing winamp recently and other than that I didnt change any soft or hardware.
