Hmm, this is very annoying.. I've started to use wxWindows 2.5.2 for the
windows builds, which has lead to this problem. When I find the time, I'll
switch back to 2.4.

Ups, overlooked that. I'll take a look at it.. Strangely, the same thing
happens if I just use PTOptimizer on the script. If I set the initial b to
some number significantly different from 0 (0.1 or so), it works, but else
it fails on the command line as well. If I set it to a really small number,
like 0.0001, the b estimate goes berzerk and I get a rms error of ~144,
where

I don't remember the old optimizer did stuff like that, I'm using the new,
panotools 2.7a-2 rpm from bruno's site. Maybe its a bug somewhere inside
the improved optimisation?

Hmm, yes, it'll compare the exif hfov with the probably optimizied hfov and
will decide that its a different image...

hugin needs a lens dialog and a preferences screen, however, I barely have
the time to fix other bugs.. :-(
