[ptx] hugin&autopano Mac OSX: bugs or incompatibilities?

[J. Schneider]

Hello,
Yesterday a friend asked me to show him how to produce panoramas. On his 
Mac, I had to use the Mac version of hugin for the first time and I 
encountered a few problems that I didn't know from the Windows version.
Are these known issues or do they maybe result in incompatibilities 
(with his system - latest OSX-version afaik - or other software or wrong 
installation)?

- In both the main window and the preview window there are no buttons
   visible, except for the number-buttons in the preview window.
   (Fortunately I could activate auto update in the preferences, so the
   preview window was of some use. But the Fit and Center buttons would
   be nice to be usable as well!)
   While a window is opened the buttons are visible for a short moment.

- In the package was an executable "autopano_old". I told hugin in the
   preferences file where to find it, but I got an error message "error
   255" when I wanted to use it.

- Optimisation for a, b, c does not work. (Yes, start values were
   unequal 0)

- We wanted to adjust the perspective of a single image (typical case
   imitating a shift lens). Therefor we placed 3 vertical control points
   and let hugin optimize. For some reason pitch was not changed. When
   the pitch was changed by hand (e.g. by setting the anchor spot), it
   didn't change after optimisation either.

Any hints, workarounds, fixes, different versions? Or just patience for 
next version?
Anyway, my friend was delighted.

Bye, thanks for any help.
