[ptx] problem with auto add with circular fisheye pics.

[spec]

Hello,

 I have those two pictures:
http://www.castlesofpoland.com/5244-12.jpg
http://www.castlesofpoland.com/5244-13.jpg

When I add them to the project, I set it to circular
fisheye with v=180 (which is close to correct).

Now when I use auto add - it works fine with the points in the middle of 
the pictures, but if i point to i.e. the ends of the cross in the 
pictures it auto-adds the wrong points on the other picture and doesn't 
even display the low coefficient message. It would be much better if it 
matched the points on
the pictures after they were already remapped (in background) and then 
the new point found would be remapped back to the point on the scanned 
picture.

Or does hugin already do that and the above is just a bug?

Also hugin manages "image center shift" pretty well and I don't have to 
specify the square or the circle as it was in ptgui - is it a feature of 
hugin or just a coincidence?

Is the a program that converts .pts to .pto's?

Thanks,
Marek
