Whenever someone sends me an email with an attached wmv file, just the audio is present in Mail. In order to watch the video, I have to download the attachment to my desktop. It then opens and plays normally. I've had Flip4Mac installed for quite some time. This is a recent development. Up until recently, the attached video would show up within the email and could be played/viewed from there as well.
Anybody have any suggestions as to the cause and/or a solution?
