I ran into other problems when I downloaded SP2 for XP Pro. Initially I uninstalled it too, but that created other issues, so I ran System Restore.
I made the mistake of downloading SP2 for Windows XP (Home edition). It fouled up my Yahoo email accounts in that I often cannot open an email, and I cannot send an email, especially an email with an attachment. I have no such problem with Netscape.
SO - I deleted SP2 and also uninstalled Yahoo, including cleaning my registry. I then reinstalled Yahoo but still have the same problem.
I wouldn't be as concerned except for the fact that I have a bunch of emails in the account with contacts, codes, passwords, etc. for those with whom I deal, and I need to get them out of that address and into an address I can work with.
Apreciate any suggestions.
