my xp is running just fine, playing video while listening to music are doing ok. but sometimes when i restart the macbook and going back to xp, the mouse is kinda lagging/stuttering. when i double click an icon to open an application. it kinda stutters then back to normal. and playing video while doing some application will make the video stutters too. if the other time im turning on this xp on macbook again. it just sometimes normal, and the other time restarts could be with this stuttering problems. any idea? im using macbook 1,83 duo with 1.2GB of ram.
