Mac Mail not showing

I have Mac Mail running on my new iMac 10.5. It was working great until all of the sudden the Mail window does not show up when I click on Mail o the dock!

The Mail icon does show that Mail is running.

Very curious.

Is it minimized to the dock, down on the right hand side?
Is "Mail" showing where the Finder usually is on the top toolbar?

Finder menu bar is showing on top of screen and Mail icon is showing normally on dock.

Once I forced Quit Mail and restarted the app it worked! I guess that even Mac has strange occurences, just like Windows!

Ok, What options appear when you Ctrl+click on it?

Ok, I see you have resolved it. Yeah some similarities with Windows!
