Flash FileReference on Snow Leopard Bug
Yesterday I spent most of the day (ok, all of the day -- including sleep, total time on the bug was 24 hours) debugging an issue where parts of our app would stop responding to mouse move, over, and out events. After a lot of investigation assuming it was in the code, this article was discovered: http://www.opencoder.co.uk/2009/09/bug-in-flash-player-filereference-browse-a... Basically on Snow Leopard, in a 32-bit browser (most commonly, Firefox), the Flash player's FileReference upload dialog will cause the Flash Player to not respond to mouse moves or hovers until you (most commonly) switch to another application and then back to the browser. Throwing this out there to hopefully give the above post some more Google juice and such, and for the future reference of myself and others.
