I hate guessing but I would assume that it was some warrant positions unwinding and a few traders that unwound some positions that they picked up cheap when we had the .50 down swing.
Don't worry, this is typical for small start up companies who have to issue debt to finance ongoing operations or that have to give warrants as part of securitizing debt. If you are holding long I think you will be happy once we see the end of the 1Q08 and on into 2008.
