[Users] Terminal vim editor in claws - doesn't return edits to claws

[flyingrhino]

Hi fellow claws'ers,

I'm trying to configure terminal vim as my external editor.
Using claws 3.11.1 on Linux Mint 17.3 xfce.

I created a bash file with the content:
xfce4-terminal -x vim -f "$@"
and chmod +x it too.

Now when I go ctrl-shift-x to launch the external editor - vim pops up in a terminal ok. 
However when I go :wq to exit vim - my text is gone and the mail is blank.

If I already have partially edited text in claws mail, then go ctrl-shift-x , the text is passed on to terminal vim, but any edits I do are lost upon :wq

Surprisingly - 
gvim -f %s
works perfectly !

Please advise where I went wrong.

Thanks,
