Okay, thanks for the good advice, I won't modify the About dialog this
way. (A weird thing is that I can modify the info dictionary,
possibly because I have the correct user privileges as another poster
noted, and the About dialog does get modified. Also, I didn't notice
anything getting written to the bundle on the disk, but who knows what
could happen.)
Thanks,
Oscar
