Thanks Donne
nzwiz is not running, not sure what OIP is?
I have managed to get the software running again it was caused by me updating my the nvidia drivers and VW did not like it for some reason, I am running GeForce 8500gt ver 110.85, driver 6.14.11.0102 as soon as i went back to this driver the problem went away, also going to my original MS mouse settings corrected the problem of the screnn pulsating.
Thanks very much for your input.
Ross
