Question : Problem: Matrox G450 Gual Screen Problem????

I have 2 proline machines with the exact same problem. I insert the Matrox G450 graphics card and all seems to work, can see both screens in display options and when I "attach"  the second screen, graphics show up on the second screen.
No errors in device manager, no conflicts.

Weird part is when I move the mouse to the second screen, the whole machine freezes up?

Played around with some windows where the cursor is still on screen 1, but the window is partly on screen two and that works, can move it around no problem. Only when the mouse cursor goes across to screen 2 does the system freeze up.

Really starting to irritate me.

Both Machines are running XP Pro.

Installed it on Acer machines and it works with now worries..... Seems it was a compatibility issue with the motherboard and the card....
