Eclipse going crazy on me.

Since I have all these programmers on my friends list, this should be appropriate here. So I work with Eclipse, and I decide I want to restart my work. All my changes - I want them gone, back to repository version. So I do right-click, "team", "revert". Okay? I press "okay". Then Eclipse detects something weird has happened. "The file has changed on disk. Do you want to load the new version?". Like ... yes? Please?
