All test were done with trial versions and i had no problems saving images in full size.
That's odd, because the website mentions that the save function is disabled in the trial version. What they didn't mention was that one couldn't view the stitched image in full resolution. On the other hand, maybe I just wasn't smart enough to figure out how to do this. There always a learning curve with such programs, but there's not much point in persevering if you can't get a full rez image.
On the other hand, it might just be due to an unannouced incompatibility with my Win XP 64 bit OS. Usually if programs don't work with a 64 bit OS there's some sort of indication when installing the program.
However, even in the low rez stitches, the color and contrast were way off.
I get the impression generally, that certain stitching programs might do a better job in auto mode with just a few images, but with a lot of images you might basically be stuffed, with no recourse to precise manual adjustment which also retains some degree of automatic color adjustment between frames, for example.
Maybe I should trial this program again on my 32 bit system. (But life's too short to mess around like this!)
