I am new to QGIS and when I set up a new composer and add a map to the page nothing appears. I have pressed the render button and the up date with no results. When I print the map there is no map but the legend I added to the page is there.
I am using the latest version of GGIS on a MAC running Lion.

I was running into this problem as well and the following worked for me:
Click "Add map" from the left hand side, then draw a rectangle on the canvas, and your map should appear.
