RE: [flexcoders] ImageSnapshot and PopUpManager

Use systemManager instead of application.

Subject: [flexcoders] ImageSnapshot and PopUpManager



Hi, I have an application that has several windows that were created using the 
PopUpManager. I would like the user to be able to take a screenshot of the the 
app so I am using the ImageSnapshot class.

The application is being captured but none of the pop up windows are showing 
up. Is there any way I can achieve this?

I have attached an example of the problem. You will need to ensure that the 
project is set to require Flash Player Version 10.0 in the flex compiler 
options.

To see the problem click on 'Pop up box' then click on 'Capture Image'

Thanks in advance
