Has anybody encountered this problem before and have a fix? I'm hoping there might be something short of sending it back in. I have pulled the battery and restarted a couple times without success.
I'm heading out of country in morning and had counted on using this device overseas. Terrible timing for it to fail on me.
Thanks for any help.

Think I just ran into, and survived, what you're experiencing:
I've had a Curve for several months (8300). Worked flawlessly - until 2 days ago, when the trackball started acting funky. I could scroll up, down and left -- but not right. It would roll - but apparently not send the info to the BB, and right rolling translated into no movement on screen.
I played around with it a bit, and noticed that if I pressed down slightly while rolling right, I could feel a bit of a bumpy "grinding" feeling, and the on-screen selection would scroll right. I then read in another post that somebody had experienced dust in their trackball - and described the feeling very much like what I just described with my trackball.
Their solution was to force some high pressure air right into the keyboard / trackball area and blast the dust out. I was thinking of a canister of pressurized air, but the poster claimed to simply blow with his mouth, and clear up the dust problem.
I have at least 2 or 3 compressed air cannisters in the house, but, naturally, couldn't find any of them when my trackball started weirding out on me. So I took a deep breath, pursed my lips - and blasted away at the trackball while depressing it slightly and rolling it in all directions.
After about half a dozen such blasts, I tested it again - and all the perfect scrolling I had for the past several months was back. After two days of being crippled, it now works again like new.
All I can think is that some kind of dust or lint became lodged in the trackball mechanism, and that I was lucky enough to be able to blast it out as described above.
If you have a can of compressed air, that might work better.
I also suggest depressing (slightly) the ball and rolling it around while you blast air at it.
Good luck!
