When I drag the Landsat and vector polygon to the map, I have to zoom to each layer and can only see one at a time.  I would like to be able to place the polygon (my region of interest) over the landsat image so I can focus in on that area.  Any idea what I might be doing wrong?  Both have the same projection.

If the the Define Projection tool was used (or similar approach) was used to establish one or the other's spatial reference it was done wrong.  Define Projection is only used when you get a warning that a file doesn't have a defined coordinate system...the program will gleefully allow you to add it and most people ignore it or decide to use the tool to tell the program what they want it to be ... but not what it is.  Put each file in separate, new data frames, zoom to the extent of the layer and examine the coordinates...If they occupy different extents...then one or both are wrong.

You can also right click the polygon/raster separately and select Properties (at the bottom) and then select the Source tab.

The numbers you are interested in are in the Extent box, marked Top - Left - Bottom - Right.

Report back if you don't know what the numbers mean.
