In Flex Builder 3 Debugger Stopped Working!! people identified a lot of reasons that can lead to the erroneous behavior of the debugger in the FlexBuilder 3. In my case it was a combination of two of them:
- In the debugging properties of the project the option “run in background” was checked (see “common” tab)
- One needs to specify 127.0.0.1 ip address in the debugger connection popup window in order that the debugger can be found
