OS 10.5 - Unusual Time Machine Issue

I have been around many forums and asked Apple Support, unfortunately everyone thinks I am mad.

The problem is this.
I have a Mac Pro 3ghz Dual Quad OSX 10.5.4
3xATI 2600 Video Cards
3x EIZO 24" CG monitors attached, one on each card.

When I enter the Time Machine restore window the graphic of the worm hole is not there, I just get a white screen. Everything works OK but it is annoying.

When I move my monitors to be plugged into a different configuration e.g. 1 monitor into card 1 then monitor 2 and 3 into card 2 everything works.
As soon as I start using the three cards again everything stuffs up again.

I know this is a bit consmetic and an unusual one but I just want to be sane again.
Thanks
Del
