Hi, All. Thanks to Jim and Joe for their helpful suggestions regarding my buzzing sound at start-up. It may be a difficult one to track down as it is very intermittent.... Only happens once or twice a week and stops when Windows is loaded. I do have another question, though: I use the Backup Utility on my Windows XP Home system to create a shadow file on my removable hard-drive. Why is the "Compression" option ghosted out? Is it only available on XP Pro, perhaps? Kind Regards Ted. -------- ================================== To Unsubscribe, set digest or vacation mode or view archives use the below link. http://thethin.net/winxplist.cfm
