Within the last 2 days, whenever I send an email (with or without attachments), I get an error message with no details, and the email stays in my Outbox and does not delete once sent, but the email does get sent. I ran both my virus scan & spyware scan, & both came up with no bugs. However, within the last few days, I did install & run a registry cleanup program, and it appears that this problem began after I ran the registry cleanup program. Running IE7 Windows XP Professional PC.
