forwarded emails stuck in outbox

If I try and Fwd an e-mail it will not send. It sits in Outbox. Even if I try and resend, it does not go. I am only having a problem with Fwd e-mails, nothing else. If I copy and paste e-mail into new message, it send without issue.

Hello Danny,

We’re sorry for the inconvenience. Are you getting any errors/messages? If it is so, could you please post a screenshot of the messages/errors that the program displays and also the log from the tab Log in the Operations window (Menu->Tools->Operations)? Just select all with Ctrl+A and use Ctrl+V to copy it here.
Also please include the number of the version that you use (Menu -> Help -> About).

Thank you,
Maurice
