I use the add-on "JIRA Email This Issue" but we have a problem since i installed Jira 7.
Open a issue
clic on buton "email"
select the Recipients (To):
type* Enter key *ou clic on Preview buton
=> there is no buton to send your mail or to exit this screen !
there is 2 problems :
1- Enter key open preview. On older version Enter sent the mail and it was beter
2- When you are in the preview screen, you can do nothing.
