More On iChat Update

This may sound a bit odd, but before the update my iBook G4 had 33.? GB remaining. I know I haven’t deleted any files, but when transferring MP3 files to an external HD for my brother, I noticed my iBook G4 has 34.06 GB remaining and available. What the heck is going on? Aside from the iChat update from Apple, the only other possible thing that could have changed this was the install of an iChat extender (well, an update; iGlasses v1.3.6 to v1.4.0). So, can you please check your HD space before and after you update to this issue, and possibly verify it for me.
