Thats precisely why I mentioned the GIF debacle. I'm a genuine old fart, my history starts in late 1934, with a good memory about such dishonest goings on. It took maybe 20 hours for gifs to disappear from the net, totally and completely then, and maybe a week to fine tune png and get the first version out the door. Where is compuserve today? A footnote in history at best, but not remembered with loving thoughts. We invented the distastefull term "submarine patent" to describe what happened.
I don't really want to be involved with an entity that references additional rights, but doesn't make those readily available. Maybe I didn't look hard enough but I did look with the idea of learning what those additional rights might cost. Take care and stay well, Steffen. > _______________________________________________ > Emc-developers mailing list > Emc-developers@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-developers Cheers, Gene Heskett. -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
