Help Publishing Adobe AIR app(mac problem)

Hi,

I am releasing an adobe AIR app on my website. I have a simple link for the download that looks like:

http: // mysite .com / apps / MyApp.air

When I download the app using my vista computer and firefox i smoothly download the .air installer package and install the app no problem.

Then on my mac book I try and download the .air app using safari. When i download it using safari, safari puts a .zip in the trash called MyApp.air.zip. And then in the downloads folder there is a folder called MyApp and all the installer package artifacts(MyApp.swf, icons folder, signatures.xml, application.xml) are in the folder. Obviously what should happen is just a MyApp.air showing up in the downloads folder.

When I try and download the .air app on my mac using firefox everything works fine like it does on my vista comp but there is one difference. On my mac when firefox prompts to download it says “MyApp.air which is a: Binary File”. On my vista comp it says: “MyApp.air which is a: Installer package”. So for some reason my air file is seen by my mac as a binary file and not a .air Installer package.

I then tested this problem using a popular .air application(tweetdeck) and when downloading that .air application on my mac everything goes smoothly with no problem at all.

Soooo…what is wrong with my .air Installer Package file to the point where my mac sees it as a straight up binary file but other .air files don’t have this problem???

Thanks
