Hmm. All I can say is I'm not sure I can even remember flash hanging since I lowered the stack limit using this nspluginwrapper patch: http://docs.freebsd.org/cgi/mid.cgi?20090630184146.GA39346 (btw still no words from the nspluginwrappper port maintainer about this, or I missed them? Cc'd again...) _When_ flash hung, I usually got it back to running by doing `killall npviewer.bin' and optionally quitting ff and doing `rm /tmp/_org_wrapper_NSPlugins_libflashplayer.so*' and then restarting the browser. (If you don't do that, remaining npviewer.bin processes might interfere with later ff sessions making flash appear more broken than it really is...) HTH, Juergen
