Thanks JRR Have tried 128kbps .mp3 file and same thing happens, pictures are on average 770 x 513. It also seems to lock up my sound, I have to reboot to get the sound back, I am using an Edirol UA-20 USB audio capture device for my sound, which is plugged in to my studio monitor system. Have an AMD 1800 processor and plenty of HD space. Have no problems running Photoshop CS or Cubase SX.
