when debugging, it seems that if my flex app has an error in it ( especially when connecting to zend such as a bad http address to gateway.php ), the flash player crashes( Program Not Responding ... End Now ... Please Tell Microsoft About this Problem ... Send Error Report ).
if I Run the app, I simply get a Error dialog box, which I can Dismiss without the player crashing.
typically in flash the flash player does not crash if there is an error ... I must be missing something, a setting.
in Run Configuration I have Main/Use Default un-checked, and pointed to ...bin-debug\my_flex.swf
That is definitely a bug.
Can you please list the exact version and type (standalone, air, plug-in) of flash player you are using?
The stack at the point where it crashes when debugging (you'll get it in the popup if you run the app in the debug player) will be crucial.
