Browser hangs/crashes when exiting video chat

i have a video chat application and on termination of the chat i want to redirect to a different html page using navigateToURL(). when the redirect is called the browser just hangs forever showing a busy cursor.

at the time of the redirect the camera is unattached and inactive.

this does not happen when i call the function from a non-video application and i think it doesn’t happen on windows either. seems to be a mac only problem and it seems to be related to using a camera and/or a netstream to deliver the video.

the video chat connects to a flash media server v3

i am using flash 9 revision 115 on a mac os x 10.4 intel system, the application is built using flex 2

does anyone else experience this problem or has a hint regarding a solution?

thanks a lot!
