Got the same problem. You can work around it by debugging in the Flash Player itself, not the browser plugin.
Hit the arrow next to the debug button. Select 'Other...'. Then you'll see a window with all your applications. If the one you want to debug is not yet selected, do so now. On the right hand side you can now see a field 'URL or path to launch' with the checkbox 'Use defaults' selected. Uncheck it and on the line that's named 'Debug:' go to the end and change the html extension to swf. Apply changes and hit 'debug'. This will launch the Flash debug player (if that's the one you've installed), not the browser. hope this helps already Max --- In [email protected], "tom_lefroy" <[EMAIL PROTECTED]> wrote: > > Hello guys, > I am utterly frustrated trying to debug flex/AS project in Flex > Builder 3, I get the following message (even when I pick run, not > debug) all the time: > > I am so tired of this message... > > "where is the debugger or host application running?" > *Localhost > *Other Machine > Enter IP adress: > Connect/Don't Connect > > I did one heluva googling on this one and still can't solve it. > > 1.
