Email open & close

I had to reinstall my Notes Client, same version and mail template as before.

Before this reinstall I could open an email by double-click on the email in my mailbox and close it again by RIGHT double-click on the mouse and return the mailbox. Now this doesn’t work anymore.

Not exactly a ‘critical issue’ but very anoying nontheless. I can’t find how to correct this again.

Tnx. for any help!
