Guys, seriously, Flash Builders hangs in all our machines like 4-5 times a day. If you press CTRL+F2 to terminate the debugging session, it hangs 1 in 2. I think that you have serious problems with the multithreading.
Debugging is hellish, more or less 10% of the times it can't connect with the debugger and gets stuck in the 57% (waiting to connect).
The bridge between the debugger and the flash player is weak! For instance, If you close the browser before the connection with the debugger, flash builder doesnt realize it and hangs (not responding...)
Why do you have so many problems with the Flash Player connection??? You need to drop the current approach and choose something more solid!
In overall, the flash builder experience is poor.
I still remember the bug:
http://bugs.adobe.com/jira/browse/FB-16153
But you didn't launch a new flex in order to solve it. We waited for Flash Builder to come. And it is still weak!!!!!!!!!!!!
Mike Morearty has let??? Who is working in Flash Builder? Please, make it rock solid!!!
And, by the way, I love Flex 4. The spark skinning. The states syntax. The two-way binding. It is incredible! You have improved over the Microsoft work in WPF. It is simpler and more elegant. Please, repair Flash Builder.
