Hi, I'm using a sparc powerlite which is a sparc laptop and it works great in stand alone mode. However, when I use an external monitor (plugged into the back) the screen shakes significantly whenever there is disk activity. Its pretty major interference - any ideas as to what that might be - or if there is an easy cure (maybe replacing the HD?) Thanks Ian. ____________________________________________________________________________________ Need Mail bonding? Go to the Yahoo! Mail Q&A for great tips from Yahoo!
