You can open multiple different AIR applications but are unable to open two of the same appliction. (This is by design)
Are you asking whether you can open two instances of the same application? If so the answer is no.
Edit: If indeed you are able to open two of the same application (even if it's a bug) please upload an example as I'm sure others would be really interested.
Thanks for the reply.
Yes I am developing an application for notification like 'TweetDeck'.
When I open the application, it search every 10sec for new notification.
If my system goes idle my applications shortcut icon on system tray not working.
If I again click on the icon on the desktop there are two icons appears on the system tray.Why this happens so
