My brother's Ubuntu Lucid machine:
Firefox stopped giving the "play" button on (eg) BBC radio and TV programs. Works fine on his Windows machine but not Ubuntu. Also works fine on my two Lucid machines here so not specifically a Lucid problem.
He switched to Opera but the same thing, suggesting it's the basic Flash installation not a browser problem.
Between us we've reinstalled Flash a few times (mainly via Terminal but also through a Firefox dup-detection add-on). Also carried out a cross-check between synaptic lists of installed Flash functions on his machine and my laptop. He has all of mine plus a few others that are probably not relevant - ie, not specifically flash core apps.
As usual, nothing relating to the exact problem on any forum we've looked at. :(
Anyone have any ideas on this, please?
