Thanks so much! I'll try those suggestions. I didn't realize this board was so active - I just downloaded the game (after having played it a few hours about 8 years ago, lol) - out of curiosity and nostalgia. Looks like there are still a fair amount of players, even some leveling, maybe alts. Very cool!
Just an fyi, there is a hardcore event currently going on that is it's own server, so the normal servers may seem less populated than normal. As people finish their hardcore journeys they will come back to the live servers.
Also, you can change what lets you move the camera like that to whatever you prefer. iirc the option is called MMO Interact/Orbit (options > keymapping)
