I am working on a large model and everything went fine until the model went over 10MB. sketchup started to crash and produce bug splats. It also says that the file I'm working is locked by another user, and won't let me save changes to the model.
Can anyone tell me why these things might be happening?

Thanks,

Oh god, don't remind me... I once had a 130 MB model, imagine how that was...

What Sketchup version do you use?
