I talked to my programming prof about this, and he thinks the fact that
I'm using a 64-bit OS might have a lot to do with it. I'll try
installing the 32-bit version of Ubuntu Studio at some point this week
and see if that changes anything (I keep all of my data on a separate
partition, so it's not a huge operation for me).
