Indeed, I get that as well. Well, I used to, since now I just hit Escape and then load a save. I think the death message actually suggests this method, though I could be mistaken.
Saves in Beyond Divinity and Divine Divinity are famously large. They get larger as you progress: by the end of the first act mine average 50 Mb each, so it does add up. Nothing to be done about it. <img src="/ubbthreads/images/graemlins/suspicion.gif" alt="" />
