LimeWire Version 3.3.5 / ATI Video Card / Windows XP SP1 - video driver fails (XP recovers from fail but you need to reboot to restore full video and colour resolution) if LimeWire running with any application using DirectX 9.0. My video driver fails with either Windows Media Player if visualisations running or if a screen saver kicks in that is using a visualisation. This is repeatable problem so there is a bug and system is absolutely stable when not running LimeWire - even if it is installed.
