How can I tell Flash Builder to debug a SWF in a new browser window?

In this case it's Chrome. I've had a look at Chrome's command line switches and the one I'd need Flash Builder/eclipse to fire is开发者_运维技巧 --new-window. Makes sense of course.

So I go into Flash builder, go to the browser preferences and set the parameters for the Chrome bin app, like so:

So that, to me seems right, but it doesn't do what it says on the tin. So what am I doing wrong and how can I get it to launch in a new window?

On MacOS X, Chrome only starts once. So, with your startup options, you get this error:

Unable to obtain profile lock.

The origin of this error is explained here.

A solution is to use a different data dir for your debugging sessions:

--user-data-dir=<PATH TO DATA DIR>

For example in your home directory (something like /Users/username/chrome-debug-datadir). That solved the problem here. You need to configure Chrome once in the new data dir. It also gives a clean separation between developing / debugging sessions and regular Chrome sessions.
