I have dropped our facebook flash game down from flash player 10 to flash player 9, just to hit as many users as possible.
However, in our web page we set the minimum version and post up the expressInstall.swf if the version is incompatible. Should we just set this to 9.0.0, or is there a later build of 9 that would be best.
Looking here: http://en.wikipedia.org/wiki/Adobe_Flash_Player would suggest 184.108.40.206 would be the 'safest' version with security fixes.
I might be making mountains out of molehills here, and the security aspect isn't worth worrying about, but I'm interested to hear what other people have done and if there is a good reason to go for the latest version of the older player, the oldest version of the latest player, etc..
Any feedback appreciated,
