you NEED to do this
OK
So you're running mac osX right? If not, stop reading right here.
OK for the rest of you, open your Terminal (if you're in the finder hold down the apple button (the command button) and the shift key, and the 'U' key at the same time. This opens your Utilities folder in your Applications folder. Then type 'ter' and you should have the Terminal program hilighted. Hold down the command button again and press the 'down arrow' button on your keyboard. This will launch the application for you) -- or you could use the wonderful and free program Quicksilver to launch Terminal, by typing not much more than 'T' and hitting return.
Either way you do it, now the terminal is open.
Copy and paste this line into it:
defaults write "Apple Global Domain" AppleScrollBarVariant DoubleBoth
Then hit return.
That's it.
You can quit out of the terminal now.
When you log back into your account, you'll now have arrows at both sides of your scrollbar. You no longer have to choose between having the 2 arrows at the top or bottom... you can have them both!
Doesn't that just make you feel better?!
What if you want to go back to the way it was the old way?
Well, you don't even need to go to the Terminal and copy and paste any text if you don't want to - instead you can open your system preferences, and just choose to have the arrows on the top or the bottom.
No harm, no foul.
I can't remember how long I've been using this, so I figured I'd pass it along to anyone else who wanted to know about it. It's not _too_ geeky!
