I also experience this though it only happens about 5% of the time for me. I'm debugging my Flex app running in the standalone Flash Player 10.
* Usually, my flex app takes a couple of seconds to launch once the workspace has finished building. * About 20% of the time, the flash player window comes up and the app then takes about 10 seconds to actually start. * But about 5% of the time, the flash player window comes up and then the app never actually starts (waiting at least a couple of minutes). If I then disconnect the debugger, the app then immediately starts as normal. Its like the debugger is blocking something. So no need to quit Flex Builder. Just disconnect the debugger. -- View this message in context: http://www.nabble.com/Flex-Builder-debugger-problems-tp21630232p21637075.html Sent from the FlexCoders mailing list archive at Nabble.com.
