Understood ( though in this case I'd happily leave them behind
for posterity )

Understood ( we just saw this from a slightly different aspect )

There was no intentional ass-out-of-u-and-me from
either side  ;o)  However, with all due respect, maybe
a little pedanty creeping in here?  ;o)   IE does 'play'

I agree with you, no, by default, IE does not play
webm ( yet ).

In which case, no more needs to be said on the matter.

Cheers for your messages and assistance.  Rest assured,
