problem with focus of the images in C1 Pro 4.5.2

I have 4x 2.5 GHz PowerPC G5 and Leopard 10.5.5 and CaptureOne pro 4.5.2 DB for P21+
There is a big problem with the preview.Actually the preview is OUT OF FOCUS after the loading of the images.I tried the previous C1Pro 4 and no problem!!!
Has anyone noticed such a "mulfunction" Cannot solve that problem.My display is a Eizo CG210 note:the problem is in normal view not in 100% view
thanks for your time
