<<I have the same setup, and it works for me. There has just been an update to Flash as linked by Ubuntu. Has this made any difference?>>
Am leaning towards MJ's opinion re Flash. But I'm on Hardy Heron still Tim so I doubt the update you've got will be relevant for me yet. (Doesn't affect Chrome btw.)
Incidentally, can anyone provide a step by step, easy to follow (for which read fool proof!) way of extracting tar.gz files? I'm not sure I've got it right... (This is the debug file from Adobe.)
