Every time I download this version of AirRadar in my browser of choice, OmniWeb, the .dmg file shows up at my end with an extra extension on the end: .bz2.

If you try to expand/unarchive the file, what you get is a messed up file that will not work.

The cure: Simply remove the .bz2 extenstion and OK the change in MOSX. The result is a correctly named and functional .dmg file.

I have notified Koingo and OmniGroup. I have never seen this phenomenon before in any browser. Omniweb does not create this problem anywhere else. Safari downloads the .dmg file perfectly fine. I have not tested other browsers. Both Safari and OmniWeb use WebKit, different versions.
