Working fine here: Mac OS X 10.6.8, Safari 5.1 Firefox 6.0.2 Chrome 14.0.835.159 beta. Also, my still unpublished web game works fine after the plugin update.
The only gripe I still have about this whole plugin updating thing is its stealthy behavior, which I find really impolite. I strongly believe users should be at least notified, if not even asked for permission, when executable code is updated anywhere in their computers, much more so when it’s done in system-wide installation paths. Not doing so is just flat-out setting a bad precedent, in my opinion.
