Does Flash Builder 4 Profiler work with a Flex 4.5 project?

I'm trying to use the Profiler for the first time so I don't know much about it. But it doesn't seem to work.

I run my project under profiler, it says it is running, but no wind开发者_运维问答ow shows up. Nothing. I can see the project's icon down there but I see no window at all.

Can this be cause by the fact that I'm using Flex 4.5? Or am I missing something?

Updated: Here's a screenshot of the Profiler running the an app. You can the app in the dock and it shows its live objects, but I don't see the apps' window and cannot interact with it. The app is just a simple 400x400 window with some black shapes in it.

Thanks in advance, Nuno

I think your problem is that you may not be running it in a debug player. Check to make sure.

It could be related to this question. It seems the profiler doesn't work well with Flash Player 10.1.
