Just last week, my laptop hard disk was replaced and XP Pro installed by a professional. Everything was working better than it ever had, until yesterday when I imported all my old Outlook Express 6 folders (with the help of a Microsoft chat support). Now, as I type, even at this moment, the screen text lags or hangs considerably. This occurs in all the applications I've tried: WORD 2007, Outlook Express 6 and as mentioned, right now!!Why?Let me add that I removed hundreds of MGs worth of messages from my Outlook, thinking that this might help. But to no avail.Thanking in advance for help,EditorMA1 person needs an answerI do too
