Bunch of Questions

I'm a fairly new player... just figured out how to get leveling to work... and suddenly there's Bear in the area. It's wiped me twice and I've gotten away (kill client) twice. Is there anything a Bear dislikes that can encourage it elsewhere? Too much time invested in my little plot of land... too much silver spent to just move out; but my Blood rating is only 15... and my Phelm 9... (working on it)
Second, if two creatures are going at it... Bear/Deer or snake/rabbit... can you take advantage of it? If I tag either one... will the loser's corpse still be on the ground when it's over?
Final question- Mouse for Camera rotating... I saw in the UI... press the 'middle button'... but for me that also the scroll wheel and the most I've been able to turn is about 10 degrees. My 2nd is a trackball... which doesn't have that much. Recommendations? (Figured this one out... goofed. Just use Trackball 99%... )
Thanks
