I have noticed when i resume from Standby on my PC that Windows Vista RC1 changes the Screen Resolution to the smallest. I have a ATI RADEON X800 GT Graphics Card. But as far as im aware Microsoft have made official support for this hardware so im taking this may be a Bug in Windows Vista RC1 ? To solve the problems i just stopped it putting the "Display" to sleep. Can anyone confirm this is a Bug in microsoft Windows Vista RC1 ?
