mouse over the mini map and use mouse wheel to zoom out?  or the minus button next to the map to zoom out?

sorry if i misunderstand the q

I must of figured it out when i played with my options its fine now.

edit: not true it happened again!

You can use your center mouse button to change perspective on the mini map. you most hold it down for it to work. You can also zoom in and out by using your scroll wheel.

If you do not have a clickabale center mouse button I'm not sure if there is another way.

Took me a long time to figure it out as well, not exactly intuitive.
