Another possible cause of my software problems could have been Nortons Internet Security 2004. I recently installed it and immediately had troubles with it, the first being that it would not scan for viruses, and then it refused to let me access the options though no changes had been made to the administrator priveleges etc. I finally got it to run properly after 3 installs, but then various other programs seemed to occasionally malfunction for some reason. I've since uninstalled it and reverted to 2003 again cos it became temperamental and behaved strangely: ie, sometimes wouldn't let me log on to change settings. Since going back to 2003 for the time being, I've had no problems at all. It may be that I have a bad copy and my comp store say they'll exchange it as others have reported similar issues. So if anyone else finds their 2004 copy become temperamental and is causing problems, perhaps an exchange for another copy is the solution.
