'The database file is locked' with System.Data.SQLite

I am suddenly getting the following errors from SQLite after adding a new transaction:

The database file is locked database
is locked

Has anyone seen this? I added an update transaction (following some successful selects/inserts). I can't find anything different about this one...

I figured it out. From looking at this [really old] thread on the phxsoftware site, it seems like there can be locking problems if you don't immediately dispose of readers and commands after executing them.

I fixed my problem by making sure to not keep commands or readers around and surrounding them with using statements.
