Does your app do a data service call on start-up? Perhaps you have a security problem that is causing an error on the non-development system, and the release player is not displaying the error.
Try to run the app on a non-dev system, but use the debug player.

I'm experiencing a strange issue: I'm not able to run my Flex app using the release player (I tried Firefox2/player 9.0.124, IE5.5/player 9.0.47 and IE7/player 9.0.124). The page contains a blank swf (when I right click I can see the Flash player menu). The same application works in all browsers using a debug player. The swf doesn't work even if I try to access it directly, while I'm able to run other Flex applications both standalone and using the HTML wrapper. I'm using the Flex 2 SDK hotfix 2 command line compiler. I actually don't know what has caused this behaviour since I use a debug player 99% of time... a colleague discovered this while testing the application. A possibile hint: this morning, using the debug player, I saw a popup window prompting me for the location of "the debugger or the profiler": this happens occasionally and, until now, I didn't pay much attention to it (don't know exactly why it appears, I'm compiling using the same options since many months). When I switched to the "runtime" player the swf seemed to freeze at the same point, though in this case I didn't see the popup window. Maybe this window and the blank page issue are related? Obviously I cannot force my customers to install a debug player ;-) Any help appreciated. Bye, Andrea
