Thank you. This was checked. I unchecked and re-checked it. The calendar appeared on top of email, but when I opened my browser, the browser covered it.
Never-the-less, what it used to do that it no longer does is this: When I would set an alarm under Tasks, if the alarm went off, it was hidden under all the open windows and did not stay on top. I only use Rainlendar as an alarm/reminder tool, not for anything else. I don't do any other kind of calendaring or tracking.
How do I make it do what it used to and stay on top until I respond to it?
