[Users] Cannot open attachment in sent mail

[Nicolas Iselin]

Hi, 

I am quite new to Claws Mail and maybe I am missing something obvious.
I have some Mails in my "sent" Folder where I have added attachments.

I would like now to open the attachment when viewing the sent mail. But
a right-click on the Attachment (in the Attachment Tab) offers only
"add", "remove" and "properties". Using copy&paste of the path and
going to the command line, I manage to open the attachment. 

But there should be a simpler way, similar to a received email. What am
I missing?

Regards 
Nicolas

PS: I am using Claws Mail 3.7.4
