This is related to Flash player, but basically to have multiple files open in Flash Player quickly decimates its performance as it seems to thread extremely poorly. However, this can be easily circumvented by either opening files in other programs that use the Flash plugin (such as browsers), or simply copying the Flash Player app a few times and dragging each file onto a different one to open multiple copies. Now, while the latter is the better option IMO, it's messy and you need to recreate the copies any time the Flash Player is updated. What I'm wondering is if it would instead be possible (perhaps via a script assigned as the .swf file type handler) to open a new copy of Flash Player every time a .swf file is opened, and hand the file to the new copy, instead of simply opening new files in an existing copy. Don't suppose anyone has any ideas as to how this would be done? I've wrestled with assigning a script container to a file-type before and it is possible (with a bit of work), but opening a single copy of an app multiple times is something I don't know how to do.
