Rated 4 out of 5 stars
Since today I realized that it is not possible to answer at emails with attachment. The reply-header appears for a second, than the message-window and the "to:"-line are empty.
Thank you for fixing this Problem nearly.
Unfortunately the review system doesn't allow me to help since I can only reply once. I have had other users report a similar issue and we corrected it by changing some system settings. Please send me an email so I can assist you. (There is a support link listed on the add-on page.)
