The edit conflict interface doesn't indicate whether forcing one's edit through will preserve the edit by the other user or will wipe out the previous edit. Since it doesn't say that the previous edit will be preserved, I have found it best to temporarily save my edit, and back out from it, and apply it again. If the edit conflict interface is meant to preserve the other edit, it should say so. ~~~~

I have the same problem, which is why I'm dropping this gadget. Preventing an edit conflict should make clear about where my comment is going and this interface has never successfully done that for me.
