A question arose whether a 50 year old abandoned well was plotted correctly on 
our maps.  The well file had a map showing the location in reference to the 
rivers that surround it.   I thought I could easily register the image & 
determine if the well was truly plotted incorrectly.  I realized when I opened 
the scanned image, that I forgot to rotate the image.  I decided that I could 
still register the image; I just had to turn my head between the images.  I 
expected the raster image to rotate to fit the map window; well, the map window 
rotated to match the orientation of the raster image.

I ended up with a map window where north was to the right.  At this point, I 
had determined that the well was located correctly & I closed the raster image; 
I thought was that this would refresh the window and the window would again be 
north to the top.  Wrong again, north stayed to the right.  Zoomed in, zoomed 
out, panned right, panned left-- it stayed to the right!  I created a layout 
window - north to the right.  I cloned the window-north was up??

I guess, I found a way to rotate a map or layout windows.  This rotation was 
about 90 degrees.  I didn't try to find if there are threshold limits to the 
rotations; but I certainly was entertained by some of the results.
