Re: [flexcoders] Re: Is Flash a single thread application?
I can't find the document explaining this, but I've certainly seen it somewhere before (perhaps at a conference?)... the basics is that the Flash Player is definitely multi-threaded, its just the ActionScript code that's single threaded (probably what the original poster got the impression from). The Flash Player has a rendering thread, a networking thread (well, probably multiple networking threads like a web browser, one per connection), and the VM thread. Troy.

[flexcoders] Re: Is Flash a single thread application?
I don't know of any specific documents, but just to clarify, in addition to Abdul's comment: Flash Player is single threaded except in the case of remote calls. Remote calls are always asynchronous by way of spinning off a separate thread. Not sure about any limits on the number of threads that can be opened in that fashion.

Re: [flexcoders] Re: Is Flash a single thread application?
So maybe this would be the area causing some of us to get Connection already in use errors in the flash player when we have more than one flex application open?
