Purchased APP2 and installed it into Fedora 10 Linux. Has several bugs.

1) Program crashes when occassionally rendering without any known reason.
2) Error message about a file qt 4.5.1  being experimental and not accepted.
3) In Browse Folder, checking don't mix landscape and portrait does not change the final finished output file name from including both types of files
in the total mix when creating the final pano  name. (i.e. 10 pictures half landscape and half portrait are processed into the output file name.) Should only indicate that
5 files were used in picture created not all 10).
4) Grouped by focal works but some pictures were shot at different shutter speeds ( i.e. I have unrelated pano pictures taken at same f/stop but different shutter speeds which comprise
different pano's, but are grouped together by the software indicating one  which is not correct). Two pano's are actually there. I have to manually regroup many photos to separate them into different panos. Final output file shows all pictures were used in the creation of the finished pano file name.)
5) When thumbnails are grouped they are group mixed (i.e. both landscape and portrait) together.) This should't happen when Browse Folder has don't mix landscape and portrait button selected). 
5) Button selection controls don't work responsively. Program will not respond when trying to stop some processes. Continues to render when incompletion is necessary. Program will appear to lock up indefinitely and computer has to be rebooted.

I'm  sorry these seem generalized in fashion. I don't have the time at present to be more specific in nature. Hopefully these fixes will be incorporated into version APP 2.1.

Other than that I wish you continued success with this program.
