MMM I think something is different.
Unfortunately I ain't quite smart enough to figure it out on my own.
I used to create PTviewer html that just showed the jpg pano image created by Pfactory like this
http://www.sembrot.com/countryside/ptviewer/index.html
Then after the recent update my Ptviewer panos look like this
http://www.sembrot.com/virtual/52williamhenry/ptviewer2
I went on the internet and found a way to limit the viewer field of view
http://roger.frebault.free.fr/Panoramique/PTViewer/PTViewer_tiltmin_tiltmax.htm
and it worked
http://www.sembrot.com/virtual/52williamhenry/ptviewer
My questions are:
1. How can I get Pfactory to handle the image the same way as the first example. ie. Limited field of view
2. Since I am specifically using single row cylindrical panoramas should I just use the .IVR format?
Thank you for this resource.

In your newer panorama at http://www.sembrot.com/virtual/52williamhenry/ptviewer2 it looks like you have selected Add top and bottom caps to saved image on the PTViewer settings dialog box.
Top and bottom caps allow the user to look up to the zenith (north pole) and down to the nadir (south pole) even if the vertical field of view is less than 180 degrees. The caps may be set to a color or to an image. The caps are white by default.
To make The Panorama Factory show the image without the top and bottom caps (as in http://www.sembrot.com/countryside/ptviewer/index.html), open the PTViewer settings dialog box by pressing the PTViewer settings button on the Save image as dialog box and turn off Add top and bottom caps to saved image.
As far as whether to use IVR or PTViewer format, the choice viewer format is up to you. Each format has advantages and disadvantages.

Without even checking the software, I know that I have seen their empty and checked boxes.
Muchas Gracias,

Here is what I wanted. Thanks for your help they all seem to be coming out fine.

I am currently researching the auto exposure mode and exposure matching. Every time I use it the images are really washed out. I am using an editor on the one or two photos that come out bad in a batch. I may also start shooting in RAW format for this reason.
How about autospinning the pano. I see that you can write in a code, but it seems like a lot work. The thing is though that I have been present when people view the links and I would say that 10-20% of the people have no idea that the picture moves.

I'm glad you solved the problem!
You mentioned that you are getting washed out pictures. You sometimes get this washed out effect when you use automatic exposure on your camera and there is a large variation in brightness between the pictures you use for your panorama.
As you suggest, the washed out effect sometimes results from The Panorama Factory's automatic exposure matching or exposure correction function. These settings work well for most pictures, not not for all.
For example, when one image contains a bright window, your camera compensates by darkening that image. If an overlapping picture is in shadow, your camera brightens that image. The Panorama Factory tries to balance the brightness of the two images to get a good match. If the brightness variation across the entire panorama is too large, The Panorama Factory's brightness matching sometimes produces this washed out effect.
Sometimes you have to disable exposure matching, exposure correction, or both to avoid the washed out effect.
You can read the help page Controlling automatic exposure correction in the section Correcting stitching problems for more information.
