First lmust explain I am very ignorant on computers/software. Having trouble with Windows Explorer 6 and Outlook - many links will not work, making many websites, eg. Microsoft Support unusable. Eg. if click on web addresses in e-mails don't work- have to cut and paste. Worse is buttons don't work - get a blank dialogue box. I've gone through Internet Options with ISP adviser , no difference - they're stumped. I am on Windows XP upgrade of Windows 98 (1st edition). Can anyone say what to do?
