Hey there,
I have the problem that an older application of mine (written more than half a year ago) does not work any more due to the URLLoader not triggering any events.
This is basically my code:
_loader = new URLLoader();
_loader.addEventListener(Event.COMPLETE, completeHandler);
_loader.addEventListener(Event.OPEN, openHandler);
_loader.addEventListener(ProgressEvent.PROGRESS, progressHandler);
_loader.addEventListener(SecurityErrorEvent.SECURITY_ERROR, securityErrorHandler);
_loader.addEventListener(HTTPStatusEvent.HTTP_STATUS, httpStatusHandler);
_loader.addEventListener(HTTPStatusEvent.HTTP_RESPONSE_STATUS, httpResponseHandler);
_loader.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler);
_loader.load(new URLRequest("Any VALID URL, nothing works."));
The code is definitely called.
But not a single event is fired. No error, no progress, no success, no crash, nothing. I’ve got nothing to work with, here 
I tried completely removing and reinstalling Haxe & OpenFL, but it just won’t do anything.
I tried under linux as well as under Windows (the program also uses the sys library, so I can’t test Flash), without success.
