That is correct, we arent looking towards moving backwards, but forwards.
Im living now with modern gen Amigas, or friends with classic amigas running OS4. Dont have this, maybe support your current Amiga developers and hardware makers then.
I would have assumed most users would be sick of living in the dark ages when it comes to browsing the internet.
As far as I know, no further updates have been made to IBrowse since Ive come back onto the scene a couple of Years ago after using workbench 1.3 so many, many years ago on an A1000.
Cheers and sorry to dissapoint what seems to be another classic user. Maybe get one of your modern supporter OS4 friends to email you the PDF or SabreMSN it to you.
