Hi all, great component but I\'ve spent (quite) some time figuring out some really annoying bugs.
First one:
If the menu item for the component is set to anything other than public, then the Paypal IPN callback will not be allowed to happen. The callback will be redirected to the registration page, which means the payment will not be confirmed.
Second one:
If you put a newline in the \"Thanks email subject\" box, then it will break the email. The mosMail function will reject the email because of the newline in the the subject. There is no indication of why this happens, it just doesn\'t send.
Perhaps you could change the input box from a multiline to a single line box to save confusion.
