This confusion comes from using a specific domain name in the link.
This site can be reached via blitzbasic.com or blitzmax.com or blitzbasic.co.nz. And such links works only after you have logged on to the appropriate one.
The better way to post links is to omit everything up to and including the .com in the URL. The correct one will be filled in by the forum software.
Thus
MaxIDE 2.04 should work for all three versions of the site.
I can't help thinking it would be better if everyone were forwarded to the same URL, presumably blitzbasic.com. It would also be better for search engines.
