Sansar isn't just difficult to use, it's terrible. You can't do anything but quit if you are stuck in the loading screen longer than you think is reasonable?
I have a pretty high end graphics card. Some experiences loaded ok, and I could move around and see stuff. But when I got to one that took several minutes to load I wanted to give up, and there doesn't seem to be any way to do that?
and the movement was weird. And can you still not use the mouse for that? I don't see any way in which this was an upgrade from a well done Second Life installation.
