Email size with an attached video

Hi I have found that version 8 when forwarding an email with an attached video the size in the outbox will be double the original mail size. Opening the email in the outbox and then sending it again cuts the size back to half. Version 7 does not have this problem but version 7 does not indicate size at all when a video is attached. I have tried this on another computer with the same results. Thanks Roger

I cannot replicate this issue using a eg: (.mp4 video file) with eM Client V 8.2.1237 for Windows.

What version of eM Client do you have ? and what video format / extention are you forwarding ?
