Windows multiple monitor icon problem

Hi everyone!

I got a problem since I've formated and it's starting to really annoy me.

I have winXP sp1 (no sp2 didn't worked lol), I'm using ultramon an I have 3 monitors.

Before I had some icons on all 3 monitors... now each boot winxp takes the icons and put them on the primary monitor... I've been using ultramon for over 18 months now and it's set right (yes "preserve position for desktop icons" is on). Even if I save the icons positions and try to restore them after a boot winxp still doesn't care...

I've never had this problem and I hope someone can give me some tips..

thx for your time ^^
