Nintendo's president acknowledged Thursday the just-launched Wii video-game machine <A HREF="http://news.yahoo.com/s/ap/20061207/ap_on_hi_te/japan_nintendo_wii">may have a problem with a strap</A> that secures its trademark wandlike remote-controller to the player's wrist. "We are investigating," Iwata said of reports about the Wii's strap coming off as players swung around the controller, at times causing the remote to fly out of their hands. Players use the Wii remote like a tennis racket, sword and other devices to play games. The company has not decided on any specific measures to change the strap, Nintendo spokesman Yasuhiro Minagawa said.
