Just an observation, not a criticism. I shouldn't have called you a "fangrrl," I know how that peeves people. I don't personally have an OS preference. I regularly use Windows, Mac, UNIX and Linux.
Well, you have to hold down the button on WINDOWS to get it to NOT jump. Microsoft just chose to set it for JUMP as normal behavior and scroll is the alternate. Apple thought scrolling was more natural and choose to make Jumping the alternate. No difference other than the assumed behavior of the user in regards to which choice is the dominate and which is the secondary. You need to hold a button down to get one or the other on BOTH OS’s.
As for Fan Grrl... well. I ain’t a fan BOY. LOL
Personally, I use several OSs too. My Mac OS X for surfing to keep it safe. My Win XP for gaming. I love my Fallout 3. And I use Suze and Ubuntu for my server boxes and torrenting.
