I give up? You prove yourself wrong in your own answer! (YOU) said that (IE6 was developed for a old worn out unsupported OS), the unsupported OS when IE6 came was 95! 98-98se-ME and 2000 were already out when IE6 came out. It came out right before XP was on all XP cds. Its was backward compatible to 98-98se-ME but was not released for them!!
They are both outdated at this point. If you had IE 7 running like it seen on the latest RC1 release you would understand the "world of difference" as well as knowing that 98 no longer has any support from Microsoft.
At this point when ir came out no longer matters for david522. He is simply trying to get rid of the IE popup messages. I run the latest FireFox here on Windows along IE 7 on the RC1. There is a registry key that can be changed that will keep the messages themselves from coming up.
