Monitor refresh rate

I have a Dell M770 monitor hooked up to a Raedon 9600 with the latest ATI
graphic drivers. Under XP, I can run the monitor at 1152x768 @85Hz. Under
Vista (32-bit) I am only able to run the monitor at 60Hz. Also, the 'Hide
modes that this montior cannot display checkbox' under the Montior tab is
disabled so I can't overide the setting. Any idea how I can get my refresh
rate settings back?

Thanks!

I've experienced this as well... try reinstalling the drivers for your
graphics card and/or monitor - fixed mine )
