Yes, the Save routine is using GetFldState(). I'm thinking, that GetFldState would report a change even if you type something, then reverted back to the original state. So, I'm now thinking that R has nothing to do with it.

I'm going to test different scenarios in a couple of minutes...

Thanks for IsNull tip. It might be the case here as well.
