For a long time I have used a dummy message in my Outbox set to not send before a date months in advance to avoid accidentally exiting OLK by clicking the X instead of - to minimize. When I clicked X to exit, a message popped up to confirm that I wanted to exit. That has quit working. It now immediately exits with no prompt.

Can someone please explain what has happened and how I can regain my lost functionality?

Cheers!
