HD5770 And Windows 7

I have just installed Windows 7 after using XP.

I had dual displays set as 1 monitir via the control centre before but that option now seems to be gone under 7.

I can set it a extended desktop, but can only set the resolutuions for the monitors seperaltly.

I I had the resolution set over the 2 monitors (2560x1600) under XP.

Is there any way to set this up again so that I can use it as if they were 1 monitor and have the toolbar etc span the 2 monitors.

Thanks

I have sorted it.

I had to download Hydravision and do a bit of mucking around, but all is good now.

Thanks
