You say it "sometimes" does that? Hmm. I don't know what's happening in your specific case, but I can tell you, in general, how Flex Builder connects to the debugger.
When you click Debug, Flex Builder launches your browser, pointing it at the HTML wrapper for the debug version of the app, e.g. C:\MyProject\bin\MyApp-debug.html. Flex Builder then starts listening on a socket, waiting for the Flash Player to contact it. FB waits for two minutes, after which it times out. In your browser, if the debug version of the Flash player is installed, and a debuggable movie (e.g. MyApp-debug.swf) is loaded into it, then the flash player will attempt to connect to the same localhost socket that Flex Builder is listening on. If the flash player can't find something to connect to at that socket, it displays the "Where is the debugger" dialog. Things that can go wrong: - You might not have the debug version of the Flash player installed. However, please note that before Flex Builder launches your browser, it checks to see what Flash player is installed in your browser. If it's the release version, it warns you. - You might be pointing to a release swf, not a debug swf. Again, Flex Builder warns you about that; but the check for a debug swf is not foolproof, especially if you have customized the html template, or are launching a custom URL. Double-check to make sure the swf you opening is the *-debug one. - Maybe you have some sort of firewall installed that is blocking Flash from connecting to Flex Builder. I did hear one report once of that happening to someone; I think that person was using Zone Alarm. Try opening access to port 7935. --- In flexcoders@yahoogroups.com, "Diego Guebel" <[EMAIL PROTECTED]> wrote: > > Hi there, > I'm just wondering why when I try to debug my app sometimes it takes a > while trying to reach to debug player, saying: "waiting for flash player > to connect to debugger" and then it fires a timeout. > I have the debug player installed, I tried installing it again.
