I can' stay away from this.

I can' stay away from this. Following a suggestion I downloaded BT Contact (see http://www.bitmanagement.de/en/products/interactive-3d-clients/bs-contact) and installed it, then I opened http://cdmon.pagesperso-orange.fr/Obse/no_cache/Monde_One.wrl. It worked! Nice and smooth and showing all the graphics. Not only that, but the background music played.

Of course the location is still a bit buggy. Previously (using Exit Reality) I had made a made a thunderstorm roll in and it was quite dynamic and niosy. Not so far with this, and it froze several times and crashed a couple as wel. I think though that's an issue with the cdmon site, as that happened with Exit Reality as well.

But, very pleased to be able to visit this virtual destination again.  When I'll feeling better I might make an OpenSim homage to it.
