My Razer Lachesis is able to create a BSOD (Blue Screen of Death) in Windows Vista. When scrolling up and down rapidly with non-default (thx BuysDB) key settings on the scroll wheel, my Windows Vista installation will crash to a blue screen. It might just be a problem with my mainboard which is also causing trouble with my mic when running Vista. These problems did not occur with Windows XP on my older system.
