Re: Request for function

Gerard,

thanks for the detailed explanations!

Just a side note: Alexander mentioned that he is working on MNG support
for Mozilla. AFAIK the "loop only once"-method is used mainly to stop
annoying animated advertisments. As such, it wouldn't help much to just
disable one / the most common way of displaying loops, because
advertisers just would start to use another method. So I don't see any
possibility other than (knowingly) breaking the spec here and disallow
loops altogether. This is similar to how popup blocking sometimes may
also block "legitimate" popups, sadly.

Just my .02
