When I click on a Reply to Sender or Reply to Group from an incoming email, why does my PC launch my personal email provider to send the reply? It also happens when I click on the email links embedded in the dalesfhs Welcome email?

It happens if you read and reply to dalesfhs emails from a remote email provider (like hotmail) when you have also got a separate email provider installed on your PC for your normal correspondence. The solution is to use the small Reply button up at the top of the email (the one with the little drop-down arrow menu beside it). This works. You can reply to embedded email addresses if you start a blank email and copy/paste the embedded email address from the old email into the new blank email's 'To' box.
